Full report (dmesg, cpuinfo, version, /proc/dri/0/* etc...) drm-intel kernel
2013-10-13

I've compiled and tested the lastest drm-intel kernel. Lots of drm related
errors, so it seems that something similar to this bug is still present. The
good news is that there aren't noticeable hangs for the moment.

[drm:__gen6_gt_force_wake_get] *ERROR* Timed out waiting for forcewake to ack
request.
[drm:__gen6_gt_wait_for_thread_c0] *ERROR* GT thread status wait timed out
[drm] stuck on render ring
[drm] stuck on blitter ring
[drm:__gen6_gt_force_wake_get] *ERROR* Timed out waiting for forcewake to ack
request.
[drm:__gen6_gt_wait_for_thread_c0] *ERROR* GT thread status wait timed out

An error report is attached.
