Sure.. seems this error is happening frequently to gather the debug info(will send out as soon as it hits). As for the bisect it is doable when I get the time. Just need a reliable recreation of the error so the bisect is correct.

Can you please rehand your machine, and then grab the i915_error_state
from debugfs? That contains the gpu hang dump we need to diagnose things.
And the bisect would obviously be awesome.
