--- Comment #39 from Laurence Lee <rubyjedi at gmail.com> ---
I hate to resurrect a zombie thread, but I am still affected by this
suspend/resume issue. My system also reports "SHADER 0xa004021e" as a common
point of failure.

On Fedora 18, kernel 3.10.10-100.fc18.x86_64), my screen resumes from
hibernation with garbage on-screen as described in this ticket, and messages
like these are repeated in the logs:

PGRAPH][0000:01:00.0] TRAP ch 1 [0x005fbb1000 X[846]]

The only thing that works at the moment is setting nouveau.noaccel=1. Setting
nouveau.config=DEVINIG=NvForcePost=1 causes bootup to Plymouth with a black,
unlit screen.

I would really like to have a long-term solution to this, and am willing to act
upon any suggestions or patches you may have to reach that goal. Thanks!
