2.6.33-rc2: Reported regressions from 2.6.32

2.6.33-rc2: Reported regressions from 2.6.32

[Rafael J. Wysocki]

[NOTES:
 * There you go, another round of tracking regressions.  It's not too bad at
   the moment, as far as the regressions from 2.6.32 are concerned, but we have
   quite a few -stable regressions, apparently in the DRI area.
 * Regressions from 2.6.31 are still being reported.]

This message contains a list of some regressions from 2.6.32, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.32, please let me know
either and I'll add them to the list.  Also, please let me know if any of the
entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

Works fine for me on an x200s. The only issue I seem to have is that
sometimes it suspends immediately upon resume again, presumably the lid
close event is re-triggered (or something to that extent). Apart from
that, 2.6.32 and current -git works fine for me.

There is an issue in 2.6.31 where it will panic (at least that's what I 
think it does, please see more details in 
<https://bugs.launchpad.net/bugs/473876>) when you have it plugged in, 
suspend, un-plug the power cable, and then resume it.

According to <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/467877> 
it has something to do with "event_when_closed_battery", I haven't tested 
it yet though, neither with 2.6.31 nor 2.6.32. Could be beneficial for 
more people to test though.

I do that all the time, not a problem here. Tried it just now and it
worked, but did the "I'll suspend immediately again". Pressing fn makes
it wake up, though.

Thanks for the info.

Perhaps the bug that Andrew saw has been fixed since then.

I'm changing the stauts of the bug to "resolved".  Andrew, please reopen if
you're still seeing the problem with the current Linus' tree.

Re: [Bug #14887] suspend doesn't work on X200s

[Andrew Lutomirski]

I suspect it was fixed by this patch:

http://lkml.org/lkml/2009/12/20/88

but I can't test because the machine in question died right after I
built it a new kernel.  sigh.

I'll re-post once I get the laptop working again if there's still a problem.

I confirm that, as of Linux-2.6.33-rc2, this regression is not
reproducible anymore. So, you can close this bug report.

When the patch is applied to 2.6.33-rc2, the regression goes away. The patch 
fixes the problem.

I think this precise one is solved. The problem is that there are other
vmalloc in the same path that also need to be fixed.

I have a pending patch for that but as there are other reiserfs lockdep
reports to be solved, I'm trying to pack all fixes in a same
set so that they can be tested using a simple merge.

For now, I guess this ticket shouldn't be closed until reporters
can test the whole.

Thanks!

The proposed patch works for me but the bug is still present in 2.6.33-rc2 
(patch still aply cleanly in rc2 and continue to solve the problem). Have to 
wait for rc3.

This one can be closed as it's not an 2.6.33 issue  (I'm running
2.6.33-rc1 with KMS just fine)

See also  http://patchwork.kernel.org/patch/69076/ for stable patch to
fix it in 2.6.32.3.

Thanks for the update.

This one has been dropped from the list of recent regressions already.  Please
close the bug when it's fixed in -stable (or let me know if you can't close it).

If the patch doesn't appear in .32.3, please send a notification to

I don't think this should be labelled as a regression. It was already
known that we'd have less throughput for the many clients cases, it was
a trade off that was made to improve latencies.

Bisected to commit d21cd8, and reverting this commit seems to fix the
problem.  The problem appeared between -rc1 and -rc2.  It was a fix
that was pushed as part of a quota/ext4 fixes.  For more information:

http://marc.info/?l=linux-ext4&m=126197233225936&w=2

I will take a look at this to see if I can find an easy fix;
otherwise, we'll probably want to revert commit d21cd8 before -rc3.

I'm working on a fix, and have a proposed patch.  See the thread on
linux-ext4 here:

http://marc.info/?l=linux-kernel&m=126219515024315&w=2

This patch also fixes the dq_claim_space kerneloops problem as
well....

This patch has been merged to mainline.  I'm working on improving
things so that we don't lose performance by unnecessarily forcing
delalloc blocks out to disk when the (wildly overestimated) number of
required metadata blocks approaches the user's remaining quota or
remaining free space on disk, but the fundamental fix is in mainline.

(The performance hit was something I knew about when I pushed the
patch to Linus, but after discussing things with Eric Sandeen, we
figured that for users who were converting from ext3, which didn't
have delayed allocation support at all, even with the performance hit
when the user approached the quota limit, ext4 with delalloc+quota was
still better than ext3 --- and I wanted a fix in mainline ASAP.
Fortunately, it's not going to be that hard make the required metadata
much more accurate.)

This is a -stable only issue in fact, so I'm not going to track it from now on.

Please watch the next -stable announcement from Greg and remind him about this
issue if the patch isn't there.

We've already had several reports like this already.

Care to review the bugs linked to http://bugzilla.kernel.org/show_bug.cgi?id=14885
and check if none of them matches the problem you describe?

I suspect that should be fixed by commit 33814341f22 ("drm/i915: disable

So try current -git.

Yeah, me too which is why I am doing a git bisect here. What's strange
about it is that the first bisection point seems to suggest that the
regression happened _before_ the DRM merge to 2.6.33-rc1. I guess it's
possible that the bug is already in 2.6.32 but I've yet to see the
flickering effect. Oh well, back to bisect...

on which side of the merge? linus or drm? 
i.e. it is to be expected to be before the merge, (but on the drm side)
so don't get confused... or did i misunderstood the situation?

Like I said, don't read too much into the results but the current
situation looks like the regression happened _after_ 2.6.32 but before
any of the DRM code was merged to 2.6.33-rc1. I don't think that makes
much sense which is why I'm back to testing 2.6.32 more to see if the
bug is there already but just harder to trigger for whatever reason.

OK, confirmed. I can see the "flashing" bug with 2.6.32 as well. It
just takes more time to trigger than in 2.6.33-rc1. I am going back to
test 2.6.31 now.

Well, I've been using 2.6.32 day to day since it came out and never saw
this bug there. What do you do to trigger this bug?

It usually triggers when I'm building a kernel. I don't have a good test 
case for this, I just need to use the machine long enough to see a 
flash. And it's pretty hard to trigger in 2.6.32.

I am now bisecting in the middle of the i915 merge in 2.6.31 so if 
people know there are suspicious commits that I should try to revert, 
please let me know.

Well, not obviously. I will try latest git as Linus suggested.
