Example i915 error state
Unigine Valley (v1.0) has started to randomly fail on BDW around mid-July Mesa
git:
---------------
ATTENTION: default value of option vblank_mode overridden by environment.
intel_do_flush_locked failed: Input/output error
---------------
[ 561.009349] [drm] GPU HANG: ecode 8:0:0x84dffec4, in valley_x64 [2125],
reason: Hang on rcs0, action: reset
---------------
It happens approximately once every 5th run, both on BDW GT2 & GT3, both with
drm-tip kernel, and month older kernel build.
(This is too random to be bisected.)</pre>
