BTW. right now, probably as a result of this, I got:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5
(awaiting 990243 at 990230)

like in the glxgears report posted earlier today. But in this case, X

another anomalies.
