Hi, it introduced a regression against 2010-09-15-16-21 in i915. The
screen, especially in thunderbird and firefox screen elements, flickers.
Is this known/is there a patch for this already?

Hi, when I run glxgears in this kernel, X crashes. It happens also with
older releases and I don't know what is the first defunct.

In the log there is:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5
(awaiting 2 at 0)

Hmm, that's a serious error as it appears the chip wasn't initialised
correctly and failed to start. G33, this is likely to be

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
survived... Except selected text is no longer blue, but white and
another anomalies.
