Thanks a lot for gathering the error state. It looks like the semaphore code deadlocked, which should not have happened. Can you please test with the my-next branch available at: http://cgit.freedesktop.org/~danvet/drm/log/?h=my-next It contains a few fixes for races (that might cause your issue) and dumps some additional information into the error state. You need to boot with i915.semaphores=1 because they're not enabled by default in that tree. Again, please attach the error state if the gpu hangs.
