Ok, there it is, in all its shining glory.

A lot of developers (including me) will be gone next week for 
Linux.Conf.Au, so you have a week of rest and quiet to test this, and 
report any problems. 

Not that there will be any, right? You all behave now!

The patches here are pretty basic. Lots of small stuff. The shortlog 
(appended) explains it about as well as you can.

POWER, ARM, MIPS, S/390, some netfilter fixes etc.

Am I missing something or this is a real problem?

Applied 2.6.20-rc5-mm-fixes and got this problem.

Using gcc version 3.4.5, binutils-2.17.50.0.8


Thanks,

This still leaves the old regressions we have not yet fixed...

 > Status     : patch available

This is not a regression from 2.6.19, since kvm did not exist in
2.6.19.  In any case akpm has the patch and plans to merge it for
2.6.20 so I don't think anyone has to worry about this one.

I have not seen the problem since using rc3, so I guess it is ok now.
Maybe the commit 9414232fa0cc28e2f51b8c76d260f2748f7953fc has fixed the
problem, but I am not 100% sure.

Thanks for this information.

Jon, Aaron, can you confirm it's fixed in -rc5?

I know, but a bug that is not present in 2.6.19 is a regression. ;-)

More seriously, I know it's a bit borderline to talk about a regression, 
but I think listing things like crashes or compile errors in new 
functionality makes sense - especially in such cases where it's about 
tracking that a patch doesn't miss 2.6.20.

I can confirm that I haven't seen it for the last four or five days.
I've been tracking linus' tree. But, I was only hitting it about once
per day. So it is probably gone or it has become much harder to hit.

What target? I had no such problem with x86, haven't tried the x86_64 
build yet. Haven't even been able to try a boot, but the build was fine ;-)

I'm at LCA and been having laptop dramas so the fix is being held up at this
point. I and trying to test a change right now that adds an optional unmap
to truncate_inode_pages_range as XFS needs, in some circumstances, to toss
out dirty pages (with dirty bufferheads) and hence requires truncate semantics
that are currently missing unmap calls.

Semi-untested patch attached below.

Cheers,

Dave.

The patch has run XFSQA for about 24 hours now on my test rig without
triggering any problems.

I have also ran this for 24h (in patched 2.6.19.2)
and no problems noticed :)

Linus, please pull from git://git.infradead.org/mtd-2.6.git

This fixes the above bug along with a few others. It does also contain a
small amount of new code which has been waiting for a while (including
the driver for the CAFÉ NAND controller which we use on OLPC.).

My apologies for missing the merge window and first asking you to pull
this a few hours after 2.6.20-rc1 was cut; I'd been waiting for the
bitrev stuff to land, and had waited too long.

I wouldn't call this a regression.  It appears to go way back.  I also
didn't find it, I just commented on it since it does affect the platform
I work on.

I didn't think that was ever checked in.  I thought the patch was still
being discussed.

The line missing will not as far as I can see cause any problems, it
will leave some registers accessible that normaly are not, but unless
something was to try and access them that shouldn't matter.  It is of
course more correct to reprotect them after the required changes are
done so it should be put back (if it was ever actually removed).

As I wrote in my list, it is commit e4f0ae0ea63caceff37a13f281a72652b7ea71ba

Does reverting this patch help?

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=406c9b605cbc45151c03ac9a3f95e9acf050808c

If not, I don't know what to suggest except "git bisect". I don't have
the hardware you are using and the backtrace doesn't give any clues.

No, the machine locks up as described in
http://bugzilla.kernel.org/show_bug.cgi?id=7667
But it worked after additional reverting of
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3b00315799d78f76531b71435fbc2643cd71ae4c
(testted with 2.6.20-rc6).
