one lockup

on openSUSE Factory (nouveau driver 1.0.9, Mesa 9.2), since kernel was updated
from 3.10.1 to 3.11.0 (rc6 or rc7), I'm getting very often GPU lockup when
using Xorg (GNOME Shell).

As I think was pointed out on IRC, it'd be great to have a bisect, or a way
to
reproduce.

The errors in the log are of the form:

There has been some TTM rework in 3.11, perhaps this is a fallout of that.

I have also been encountering problems with the X server crashing in kernel
3.11.1 in Fedora 19 64-bit (KDE desktop).  Usually the desktop locks up and
eventually drops to command line where messages like the following are printed:

nouveau E[ X[945]] failed to idle channel 0xcccc0000 [X[945]]
nouveau E[ X[945]] failed to idle channel 0xcccc0000 [X[945]]

I've had this issue for some time. The system will work fine until the first
lockup. After that it locks up everytime I unlock my desktop(for about 30
seconds). The lockup sometimes starts or occurs when going to the top left
corner with the mouse in gnome-shell. Rebooting fixes the issue for a number of
days.

Thanks.

H.J. Lu points out that this might be the same bug as
https://bugzilla.redhat.com/show_bug.cgi?id=918732

I'm hitting that fairly often.

Allan: You have a NV92 card, and what appears to be a very different issue.

Frederic: Do I understand correctly that everything is consistently fine in
3.10.x and consistently broken in 3.11.x? If so, could you try doing a bisect
to identify the offending commit? (First might be worth checking if the issue
still occurs in 3.13 btw.) BTW, your third "lockup" log doesn't
indicate that
anything really went wrong -- just a kmalloc() failure which should be handled
by the surrounding code. Although the later xfs corruption errors are a bit
ominous... 

In any case, this is highly unlikely to see any progress without a git bisect
on the kernel (drivers/gpu/drm should be enough).

With 3.11.6, I get very few lockups (if any), which is making bisection
irrelevant/impossible to do.

the xfs corruption was caused by running mkinitrd which was trying to load xfs
module even if there is no xfs partitions anywhere (this is now fixed).

Sounds like the OP's issues are gone. Feel free to reopen if I
misunderstood.
