dmesg output with GPU hung messages
Following my report on https://bugzilla.kernel.org/show_bug.cgi?id=15671, the
bug still exists in 2.6.35.4 but is much less frequent, which could be due to
my kernel configuration (selecting some kernels options would increase the
occurrence of this bug).
I see that in this 2.6.35.4 release an extra debug message seems to have been
added "[drm:init_ring_common] *ERROR* render ring head not reset to zero ctl
00000000 head 02001000 tail 00000000 start 02001000
[drm:init_ring_common] *ERROR* render ring head forced to zero ctl 00000000
head 00000000 tail 00000000 start 02001000".
Please check the attached dmesg output for the full output.
After that I need to go to a console and "reboot", cause the screen stops
updating on X.
