I've finally managed to reproduce this problem on my box, by doing:

watch --interval=0.1 /sbin/hdparm -I /dev/sda

on one drive and then running bonnie++ on /dev/sdb connected to the 
other port on the same controller device. Usually within a few minutes 
one of the IDENTIFY commands would time out in the same way you guys 
have been seeing.

Through some various trials and tribulations, the only conclusion I can 
come to is that this controller really doesn't like that 
NV_INT_STATUS_CK804 register being looked at in ADMA mode. I tried 
adding some debug code to the qc_issue function that would check to see 
if the BUSY flag in altstatus went high or that register showed an 
interrupt within a certain time afterwards, however that really seemed 
to hose things, the system wouldn't even boot.

Try out this patch, it just calls the ata_host_intr function where 
appropriate without using nv_host_intr which looks at the 
NV_INT_STATUS_CK804 register. This is what the original ADMA patch from 
Mr. Mysterious NVIDIA Person did, I'm guessing there may be a reason for 
that. With this patch I can get through a whole bonnie++ run with the 
repeated IDENTIFY requests running without seeing the error.

As an aside, there seems to be some dubious code in nv_host_intr, if 
ata_host_intr returns 0 for handled when a command is outstanding, it 
goes and calls ata_check_status anyway. This is rather dangerous since 
if an interrupt showed up right after ata_host_intr but before 
ata_check_status, the ata_check_status would clear it and we would 
forget about it. I tried fixing just that issue and still had this 
problem however. I suspect that code is truly broken and needs further 
thought, but this patch avoids calling it in the ADMA case, at any rate.

As a final aside, this is another case where the hardware docs for this 
controller would really be useful, in order to know whether we are 
actually supposed to be reading that register in ADMA mode or not. I 
sent a query to Allen Martin at NVIDIA asking if there's a way I could 
get access to the documents, but I haven't heard anything yet.

Obviously, NVIDIA's response is disappointing, but thank you for putting the 
time in to debug this problem. Definitely sounds like a hardware defect, I'm 
just glad there's a workaround.

Will we see this fix in 2.6.20?

Hopefully, assuming it actually does fix the problem for those that have 
been seeing it..

Hm, I don't think it is unhappy about looking at NV_INT_STATUS_CK804.
I'm running 2.6.20-rc5 with the INT_DEV check removed for 8 hours now
without a single problem and that should still look at
NV_INT_STATUS_CK804, right?
I just noticed that my last email might not have been clear enough. The
exceptions happened when I re-enabled the return statement in addition
to the debug message. Without the INT_DEV check, it is completely fine
AFAICT.

I'll see if I can schedule a test run for tomorrow, I currently need
this box.

Indeed, it seems to be just the NV_INT_DEV check that is problematic. 
Here's a patch that's likely better to test, it forces the NV_INT_DEV 
flag on when a command is active, and also fixes that questionable code 
in nv_host_intr that I mentioned.

The last patch (sata_nv-force-int-dev-in-interrupt.patch) 
seems to have fix the problem.  Much appreciated, 
thank you. I'd consider it a must have in 2.6.20.

After about 1.5 days of uptime, an involuntary reboot and another 3
days of uptime, no sign of an exception. No stress testing was done,
but a few disk intensive actions did happen, at least more than with
that -rc6 that did throw an exception at me.

Got 2.6.20-rc7 with them applied now (the rejects seemed trivial enough

Same exception details as before?

There's a patch in -mm (sata_nv-use-adma-for-nodata-commands.patch) 
which should hopefully avoid this problem for the cache flush commands, 
at least - can you try that one out? You'll have to apply the other 
sata_nv patches in -mm first, i.e. this order:

Or maybe not :( Just got an exception on 2.6.20-rc6. Took 4 days of
uptime to trigger, so it's just a lot harder to trigger now.

David Chinner sent two patches regarding that bug yesterday.

I applied it yesterday and today my dmesg contains three:
BUG: at mm/truncate.c:60 cancel_dirty_page()

Seems to work for me, uptime is about an hour now and no exception yet.
Had the stress test running for only about 10 minutes, but I usually got
an exception within an hour even during plain irssi usage, so I'm quite
confident that the patch fixes it.

Thanks,

Can any of the rest of you that have been seeing this problem also 
confirm that this fixes it?

The mentioned Maxtor model (6Yxxx) isn't susceptible to the
large-buffer long completion times, due to architectural differences
and availability of only small buffers.  Any "real" long-completion
flush on this device would, I believe, involve damage to the disk that
hinders the ability to seek, settle, or write.  (e.g. 30-second
flushes are easy to hit if you mount the disk on a shaker-table with
sufficient amplitude)

Later in the thread I think people have pretty much isolated it as not
the disk's problem, but just wanted to point this out.

I assume that large enough customers can buy enterprise-type command
completion ("all commands within X seconds") from most any disk
vendor.  However, these firmwares require much smarter or more active
drivers or block layers, to handle the higher error rate when the data
on the device is valid, but it will take longer than allowed by the
arbitrary enterprise rules.  Most customers who are buying this many
devices have software engineers customizing the drivers or disk
management applications to handle this differing behavior.

No, doesn't seem to be related, did get 2 exceptions, but no irq_stat
0x0 for ata1. Syslog/dmesg has nothing new either, still the same
pattern of dismissed irq_stats.

40 minutes stress test now and no exception yet. What's interesting is
that ata1 saw exactly one interrupt with irq_stat 0x0, all others that
might have get dropped are as above.
I'll keep it running for some time and will then re-enable the return
statement to see if there's a relation between the irq_stat 0x0 and the
exception.

Running a kernel with the return statement replace by a line that prints
the irq_stat instead.

Currently I'm seeing lots of 0x10 on ata1 and 0x0 on ata2.

Yes and no, it's probably not a power problem, I've tried another
PSU with the same result :( . Futhermore, the RAID0 setup makes
it impossible to try only one drive alone :(. 

Anyway,the WD2500KS is known to have some strange bugs in the FW.
e.g.: It reports 255°C right after a cold start. 
( http://www.bugtrack.almico.com/view.php?id=468 ).

Or, you have power related problem.  Try to rewire the power lines or 
connect harddrives to a separate powersupply.  It's often useful to 
change one component at a time and watch which change the problem 
follows.  Anyways, you seem to be suffering transmission failures, not a

Hmm, another miss, apparently.. Has anyone tried removing these lines
from nv_host_intr in 2.6.20-rc5 sata_nv.c and see what that does?

     /* bail out if not our interrupt */
     if (!(irq_stat & NV_INT_DEV))

Just got two exceptions with your patch, none of the debug messages were
issued.

Yeah, I don't think just adding reads to flush posted writes is enough 
here - it seems to need more delay than that, and it also wasn't always 
in the idle state even before we would write the register..

Uhm, yeah, exception occured about the time that I hit "send".

I went for the "I feel lucky" route and did just add mmio reads after the
mmio writes, posting them. Rationale being that if it is a write posting
issue, the debug patch would/could actually hide it AFAICT.
It's the "I feel lucky" route, because my whole "knowledge" about mmio
and write posting originates from the few things I read up on when you
discovered the comment about write posting in the generic ata code.

Ok, you won't believe this... I opened my case and rewired my drives... 
And guess what, my second (aka the "good") HDD is now failing! 
I guess, my mainboard has a (but maybe two, or three :( ) "bad" sata-port(s)!  

But, one small question remains: when I opened my case, I saw that my drivers
are pluged in SATA jack 1 and 2... The BIOS also says they're on 1 and 2.
Now, Linux says they're on port 3 & 4! 



it's always ata3.00!
"ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

OK guys, here's a new patch to try against 2.6.20-rc5:

Right now when switching between ADMA mode and legacy mode (i.e. when 
going from doing normal DMA reads/writes to doing a FLUSH CACHE) we just 
set the ADMA GO register bit appropriately and continue with no delay. 
It looks like in some cases the controller doesn't respond to this 
immediately, it takes some nanoseconds for the controller's status 
registers to reflect the change that was made. It's possible that if we 
were trying to issue commands during this time, the controller might not 
react properly. This patch adds some code to wait for the status 
register to change to the state we asked for before continuing.

I run those two in parallel:
while /bin/true; do ls -lR / > /dev/null 2>&1; done
while /bin/true; do echo 255 > /proc/sys/vm/drop_caches; sleep 1; done

Not sure if running them in parallel is necessary, but I don't want to
change the test setup ;) Takes between 1 and 40 minutes to trigger it.
Most of the time it's around 15 minutes now, doing more random stuff in
addition to that seems to trigger it even easier (like reading mail,
rebuilding the kernel etc.).

I'm down to 2 commits after 2.6.19 now, only bad kernels, so I tend to
say that 2.6.19 with 2.6.20-rc5's sata_nv.c will also fail for me, but I
thought I might finish bisection just to be sure.

I get the same exception every time, doesn't change for me. And neither
do I get any SMART errors or something.

Argggg, 2.6.19 (with 2.6.20-rc5 adma stuff) is affected too (BTW, what do you 
do to trigger the exceptions? Because, it takes hours to "reproduces" this
silly *************).

But, this time it looks slightly different:
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

Ah, right... sata_nv.c of course interacts with the outside world, d'oh!

Up to now, I only got bad kernels, latest tested being:
94fcda1f8ab5e0cacc381c5ca1cc9aa6ad523576

Which, unless I missed a commit in the diff, only USB changes,
continuing anyway.

Just to make sure, here's my little helper for this bisect run, I hope
it does what you expected:

#!/bin/bash
cp ../sata_nv.c.orig drivers/ata/sata_nv.c
git bisect good
cp drivers/ata/sata_nv.c ../sata_nv.c.orig
cp ../sata_nv.c drivers/ata/
make oldconfig
make -j4

Where "../sata_nv.c" is the version from 2.6.20-rc5. The copying is done
to avoid conflicts and keep git happy. Of course there's also a version
for bad kernels ;) No idea, why I didn't make that an argument to the
script...

Thanks,
Björn

Whatever the problem is, only seems to show up when ADMA is enabled, and 
so the patch that added ADMA support shows up as the culprit from your 
git bisect. However, from what Chr is reporting, 2.6.19 with the ADMA 
support added in doesn't seem to have the problem, so presumably 
something else that changed in the 2.6.20-rc series is triggering it. 
Doing a bisect while keeping the driver code itself the same will 
hopefully identify what that change is..

I'll go for it, but could I get an explanation how that could lead to a
different result than my last bisection? I see the difference of keeping
sata_nv.c but my brain can't wrap around it right now (woke up in the
middle of the night and still not up to speed...).

Yes, 'git bisect' would be the next step in figuring out this puzzle.

Anybody up for it?

That is interesting, indeed.. If that holds up then I assume some other 
change in 2.6.20-rc is either causing or triggering this problem. It 
would be useful if you could try git bisect between 2.6.19 and 
2.6.20-rc5, keeping the latest sata_nv.c each time, and see if that 
gives any indication. If not, just trying some of the different 
2.6.20-rcX versions may be useful.

Before that, though, can you try making this change I suggested below in 
2.6.20-rc5 and see if the problem still shows up?

Ok, did that! (got a fresh 2.6.19 tar ball, and used 2.6.20-rc5' sata_nv.c
with the oneliner in libata_sff.c)

And surprise.................... after one hour uptime, there is not even one 
sata exceptions in dmesg! (I'll report back tomorrow...)

Eh? The whole point with that patch was to ADD ADMA support to sata_nv,
imho that is something we want to have and i have been running with ADMA
on on two computers since sata_nv-adma-ncq-v4 or 5 or so without
problems.

So, something has been introduced or been broken to cause this error,
wouldn't it be better to find the error introduced than to just totally
negate the patch in the first place?

I haven't had the energy to go trough the patch that was found as
causing the problem yet... I don't know if i even have all the info
needed to make any form of educated guess but i'll give it a try when i
have the energy.

I really home someone finds it before then =)

I'm still running an -rc5 kernel with ADMA switched off entirely and I can't 
reproduce the problem. How is everybody else reproducing this?

I've been successful installing bonnie++, then going to a large XFS partition 
and running "bonnie++ -u 1000:1000" and letting it run through, all defaults.

It doesn't cause the problem I was seeing in -rc5 with ADMA on, when I switch 
ADMA off, so I think this is sufficient to fix it.

Others have reported differently. Did you guys do:

alistair@damocles:~$ cat /proc/cmdline
root=/dev/sda1 ro sata_nv.adma=0

Or something similar? This is how Jeff suggested disabling ADMA and indeed the 
messages about its use disappear from dmesg.

(I'm ccing more of the people who reported this)

Well that's interesting.. The only significant change that went into 
2.6.20-rc5 in that driver that wasn't in that version you mentioned was 
this one:

http://www2.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2dec7555e6bf2772749113ea0ad454fcdb8cf861

Could you (or anyone else) test what happens if you take the 2.6.20-rc5 
version of sata_nv.c and try it on 2.6.19? That would tell us whether 
it's this change or whether it's something else (i.e. in libata core).

Assuming that still doesn't work, can you then try removing these lines 
from nv_host_intr in 2.6.20-rc5 sata_nv.c and see what that does?

	/* bail out if not our interrupt */
	if (!(irq_stat & NV_INT_DEV))
		return 0;

as that's the difference I'm most suspicious of causing the problem.

Yes, I've some reiserfs partitions, but I don't think it's reiserfs fault ;). 
Here is the log. (I cut out some parts, because it was too big.)

Hi,

I went from 2.6.19+sata_nv-adma-ncq-v7.patch, with no problems and adama

I just thought that it might be interesting to know that it DID work
nicely.

CC since i'm not on the ml

Darn, didn't remove enough stuff (hit the 100K limit), next try. Sorry
if anyone gets this duplicated for whatever reason.

Can you guys that are having this problem try the attached debug patch? 
It's possible it will fix the problem, as I'm trying a private 
exec_command implementation that flushes the write by reading a 
controller register instead of reading altstatus from the drive like the 
libata core code does.

If the problem still happens, I also added some more debugging in to 
help figure out what is going on, so please post full dmesg.

By the way, I assume that you guys are using reiserfs or xfs, as it 
appears no other file systems issue flush commands automatically. I had 
to test this by "echo 1 > delete" on the SCSI disk in sysfs, as I am 
using ext3.

Not for me.
I'm still have the same trouble, but less (maybe about every hour, instead of 
every 5 minutes). futhermore, I found a patch
cocktail-2.6.20-rc3.patch: http://tinyurl.com/2gza8q, which improves the 
situation too! 

Now, the funny thing is that I've two SATA HDDs, but only 1 causes all the
headaches.

The affected drive is a:

Setting this option fixes the problem for me. I suggest that ADMA defaults off 
in 2.6.20, if there's still time to do that.

I have exactly the same problem on -rc5 and it causes all I/O to stall 
periodically if I do _anything_ I/O intensive.

On my box, I have 4 sata_nv handled SATA ports, with two pairs of different 
drives (two Maxtor, two WD) and it happens randomly on both. So it's 
absolutely nothing to do with the drive make/model.

I'll try Jeff's suggestion of disabling ADMA now, but I think something more 
radical than this workaround should make it into 2.6.20 final, otherwise a 
lot of people are going to have broken boxes.

That would imply that disabling adma via a module parameter should make
the issue go away, right? I'll try to have a test run with adma disabled
over night then.

I heard from Larry Walton who was apparently seeing this problem as 
well. He tried my recent "sata_nv: cleanup ADMA error handling v2" patch 
and originally thought it fixed the problem, but it turned out to only 
make it happen less often.

I wouldn't expect that patch to have an effect on this problem. If it 
seems to reduce the frequency that would tend to be further evidence of 
  some kind of timing-related issue where the code change just happens 
to make a difference.

I'll see if I can come up with a debug patch for people having this 
problem to try, which prints out when a flush command is issued and what 
interrupts happen when a flush is pending.

There is one important difference between ADMA and non-ADMA mode for 
non-DMA commands like flushes, which didn't come to mind before: ADMA 
mode uses MMIO registers on the controller whereas non-ADMA mode uses 
legacy IO registers. Posted write flushing is a concern with MMIO 
registers but not with PIO, the libata core is supposed to handle this 
but maybe it doesn't in some case(s). In fact, just looking at 
libata-sff.c there's this comment on the ata_exec_command_mmio function:

  *      FIXME: missing write posting for 400nS delay enforcement

That seems a bit suspicious..

When ADMA is enabled we can't use ATAPI at all (or so says NVidia 
anyway), so it has to be disabled when an ATAPI device is detected in 
slave_config. Since doing that implies using the legacy BMDMA engine 
with its greater restrictions, this is why we need to prevent DMA 
transfers from being attempted until those restrictions have been set 
properly. (Otherwise, the libata core will try to use PACKET commands on 
an ATAPI device with DMA enabled before slave_config is even called.)

Just to eliminate things, has disabling ADMA been attempted?

It can be disabled using the sata_nv.adma module parameter.

FWIW:  According to the drive guys (Eric M, among others), FLUSH CACHE 
will "probably" be under 30 seconds, but pathological cases might even 
extend beyond that.

Definitely more than 7 seconds in less-than-pathological cases, 
unfortunately...

The SCSI layer /should/ already take this (30 second timeout) into 
account, for SYNCHRONIZE CACHE (and thus FLUSH CACHE for libata) but I'm 
too slack to check at the moment.

I wondered about it, because the flag is cleared when adma_enabled is 1,
which seems to be consistent with everything but nv_adma_check_atapi_dma.
Thus I thought that nv_adma_check_atapi_dma might be wrong, but maybe

I just checked Maxtor's knowledge base, that incompatibility does not
affect my drive.

Note that the ATA-7 spec for FLUSH CACHE says that "This command may 
take longer than 30 s to complete."

It should be correct the way it is - that check is trying to prevent 
ATAPI commands from using DMA until the slave_config function has been 
called to set up the DMA parameters properly. When the 
NV_ADMA_ATAPI_SETUP_COMPLETE flag is not set, this returns 1 which 
disallows DMA transfers. Unless you were using an ATAPI (i.e. CD/DVD) 
device on the channel this wouldn't affect you anyway.

I'll try your stress test when I get a chance, but I doubt I'll run into 
the same problem and I haven't seen any similar reports. Perhaps it's 
some kind of wierd timing issue or incompatibility between the 
controller and that drive when running in ADMA mode? I seem to remember 
various reports of issues with certain Maxtor drives and some nForce 
SATA controllers under Windows at least..

Ok, 7 seconds for FLUSH_CACHE would have been nice for us too though, as
it would pretty much guarentee lower latencies for random writes and
write back caching. The concern is the barrier code, of course. I guess
I should do some timings on potential worst case patterns some day. Alan
may have done that sometime in the past, iirc.

Yep, that one seems to be guilty. 2.6.20-rc5 with that commit backed out
survived about 3 hours of testing, while the average was around 5
minutes for a failure, sometimes even before I could log in.
I took a look at the patch, but I can't really tell anything.
nv_adma_check_atapi_dma somehow looks like it should not negate its
return value, so that it returns 0 (atapi dma available) when
adma_enable was 1. But I'm not exactly confident about that either ;)
Will it hurt if I try to remove the negation?

Thanks,
Björn

My latest bisection attempt actually led to your sata_nv ADMA commit. [1]
I've now backed out that patch from 2.6.20-rc5 and have my stress test
running for 20 minutes now ("record" for a bad kernel surviving that
test is about 40 minutes IIRC). I'll keep it running for at least 2 more
hours.

The test is pretty simple:
while /bin/true; do ls -lR > /dev/null; done
while /bin/true; do echo 255 > /proc/sys/vm/drop_caches; sleep 1; done

running in parallel.

That's not the reason. Yeah, I should not have sent a log of a run with
the nvidia module loaded, but the same thing happens without it. For the
bisection kernels I did not even build the nvidia module and did the
testing at the console.

AFAIK Windows flush-cache timeout is 30 seconds, not 7 as with other 
commands...

Agreed.

and then things start to break.

Notice how the problems started exactly at the point the
"NVRM" NVIDIA module (whatever it is) was loaded ...

I'd be surprised if the device would not obey the 7 second timeout rule
that seems to be set in stone and not allow more dirty in-drive cache
than it could flush out in approximately that time.

And BUSY should also be set for that case, as Robert indicates.

Next round of bisecting led to another useless result, a) it was an
unrelated driver, b) the kernel I just marked as good after 20 minutes
of testing decided to fail when I hit reply... Guess that it was pure
luck that the kernel I marked as bad failed within 1-2 minutes.
I send the git bisect log with this mail, maybe at least the early good
kernel are really good and someone can make some sense out of it. At
least I ended up somewhere in a series of libata changes.

Thanks,
Björn

If the flush was still in progress I would expect Busy to still be set, 
however..

Bi-section led to commit 249e83fe839 which makes absolutely no sense to
me, just in case that anyone sees any problem with that commit.
I'll go and re-check a few of those commits that I marked as good.

It's possible the flush-cache command takes longer than 30 seconds, if 
the cache is large, contents are discontiguous, etc.  It's a 
pathological case, but possible.

Or maybe flush-cache doesn't get a 30 second timeout, and it should...? 
  (thinking out loud)

Looks like all of these errors are from a FLUSH CACHE command and the 
drive is indicating that it is no longer busy, so presumably done. 
That's not a DMA-mapped command, so it wouldn't go through the ADMA 
machinery and I wouldn't have expected this to be handled any 
differently from before. Curious..

Hi,

with 2.6.20-rc{2,4,5} (no other tested yet) I see SATA exceptions quite
often, with 2.6.19 there are no such exceptions. dmesg and lspci -v
output follows. In the meantime, I'll start bisecting.

Thanks
Björn
