Title:
1002:6739 [Asus P6T] radeon 0000:02:00.0: GPU lockup CP stall for more
than 10000msec
Status in The Linux Kernel:
New
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Often, the Xorg session freeze, go to black screen, and is display
again. Most of the time Xorg stop to respond.
I'm not sure what exactly is the cause of the problem, probably some
instructions send to the GPU by compiz, which make the kernel GPU
code to be locked. So my supposition is that the kernel code can have
a deadlock situation.
The only trace of error I have is in the kernel log (the kernel itself
do not crashed):

This can loop 1 to 5 times, with a few seconds between them. This situation can happens any time, and rarely I can continue to use my session.
Like I said, the kernel itself do not crash, generally, I login using an another computer with ssh, and type "sudo reboot".
I have earch a little for that problem, I've found some, having "GPU
lockup CP stall for more than 10000msec" but they seems to not be
related to my problem.
My ATI card is an "Sapphire Radeon HD 6850 1Go", and I use the free
software driver. Using the previous version of Ubuntu I didn't have
this error.
I have almost no hope to have this bug fixed (too few infos, no one
having it), but is there some method I can use to get more
informations on this problem ? I will try a kernel debugging, but for
a "random" bug, it will be more harder. Some day it crash, some it
don't crash!
