Hello,

I bought new Athlon46 mobo with AM2 socket and recently
I noticed that copying large amounts of data reliably
crashes 2.6.17.11 64-bit on it.

memtest runs ok on this machine overnight.
Machine is not overclocked.

Copying movies from SATA drive to PATA drive oopses
after few gigabytes transferred. Creating iso image
with mkisofs (done entirely on PATA drive, no SATA attached)
does the same.

After some testing I found ou that rw load crashes
machine rather fast, while read load usually runs for several
minutes before crash. Setting udma4 or udma3 instead of udma5
doesn't help. Pity I don't have my own SATA drive to run tests
with it, ran most of the tests on PATA drive.

rw loads crashed twice on the same instruction, movl (%rdx), %eax
in fs/mpage.o, and I tracked it down to corresponding C line:

However I'm afraid it may be not useful, because read
load tests crash in random places. Reads are done by cat >/dev/null.

I obtained PCI config space dumps under Windows XP on this machine
and compared them to Linux settings. Integrated PATA IDE controller
has some differences in rows 5x and 8x. Grep for "IDE interface".

Maybe this sheds some light.

URLs to chipset docs, anyone?...

Hello lkml'ers

If you happen to have the same mobo, MSI AM2 K9N NEO-F

http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=733

and streaming disk i/o works for you, plase send me:
* kernel version and .config
* hdparm -i output
* lspci -vvvxxx output

Thanks... now with gory details.

As Alan pointed out, there aren't any obvious differences which
may affect IDE. They are mostly in AMD CPU Northbridge...

I bought SATA II Samsung drive yesterday. Created 32gb file on it.
Windows XP can do "copy 32g nul" - no problems.
The very same thing on Linux randomly crashes in a few minutes.

Please note that I was using Linux on this machine for a bit more than
a month and I had just one unexplained (at that time) crash.
I compiled stuff on it and copied a lot of files (kernel trees, for one),
without crashes. It was feeling like everything was working okay.

So it seems likely that memory corruption and resulting crashes
occur only when there are large amounts of streaming I/O, "short"
reads/writes (less than ten megabytes at once) are affected much less
or not affected at all.

BTW, I tried running with mem=500 and tried 32-bit kernels,
still crashes.

I also did a direct device-to-device copy using dd
(translation: no filesystem code involved) and it crashed too.

And to repeat: it happens both on PATA IDE Western Digital drive
(WDC WD2500JB-55GVC0, FwRev=08.02D08, SerialNo=WD-WCAL78337950)
and this new Samsung SATA drive...

Does this rings any bells? What is different when I do streaming i/o?
IOW: where should I start poking in the driver? Because Windows
somehow works, dammit... it must be possible to make it work...

I do not have another mobo for testing.

I don't know about K9N Neo, but I have MSI K9N Ultra-2F (the same
MCP55) and have no such issues. But:
- I'm not using drivers/ide anymore (I was using 2.6.17.11 with
  Alan's libata-PATA patch and now I have ca. 2.6.18-rc6 merged
  with Jeff's pata-drivers git branch)
- I have only PATA CD-ROM (and SATA disk, Seagate ST3250823AS).
- just 1 GB of RAM.

Copied CD/DVD-ROM discs to HDD few times, no problems.

Not really, but allow me to make another comment: MSI seems to have
massive problems with the K9N based boards. A good percentage of them
just "freaks out" from time to time and shuts the system down with no
aparent reason. This happens under Linux as well as under windows, and
is, interestingly, related to copying large amounts of data to the
PATA controller, and transfering large amounts of data over the LAN
causes the same problem. It thus would be interesting to know whether
for the affected board the same or a similar problem appears under
win32. If so, it's just the defective board, and not a linux kernel
problem.

Reference for the problem: Look into the MSI forum at www.msi.com, 
check for the thread "Post your K9N problems here...".

So long,
	Thomas

Thanks for everyone answered.

The problem is resolved - one DDR2 module is bad now.

One month ago it survived overnight memtest run,
but now it is definitely bad. memtest detects problems
in a few seconds.

I found info about such mobos and preliminary analysis said
to indicate that one of mobo capacitors had wrong specs.
MSI said to start replacing affected mobos.

My mobo serial number doesn't seem to fall into range of
affected ones, but entire affair doesn't sound encouraging at all.

Not to mention that BIOS is somewhat more buggy that I expected, too.
