dmesg kernel log following a boot, suspend to RAM and then resume

I am using KDE 4.6.0 on Gentoo Linux's testing tree with the Linux 2.6.38-rc5
kernel. Resuming from a suspend to RAM kills 2D performance. This issue also
occurs with Linux 2.6.38-rc4.

I discovered this while I was testing a power management patch for Martin
Peres. His patch provided a proc interface for changing my card's performance
level. If I set the performance level and suspend to RAM, the system will not
resume at all and I cannot even ssh into it. Without setting a performance
level with his patch applied, the system will resume from a suspend to RAM, but
2D performance is awful. Resuming from a suspend to RAM also results in poor 2D
performance even if his patch is not applied.

There are some messages in the dmesg kernel log that seem to describe what is
going wrong, but I do not understand them. I have attached the output.

Xorg log from a different boot

mupuf_laptop asked me to include the Xorg server log. I triggered this
condition again to generate the log.

Unfortunately, dmesg is not displaying any of the things it exhibited during
the previous boot, despite the 2D performance being poor like the previous
time.

I couldn't get this issue to manifest itself consistently with the 2.6.38-rc4
kernel earlier in the week. Sometimes it would be slow and at others it would
simply display graphical corruption. Now that I have some time, it seems that
the 2.6.38-rc5 kernel is also being inconsistent, although I have not seen any
graphical corruption yet.

--- Comment #2 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
