Can you try the patches in this thread?

Comment 4 Kenneth Graunke 2011-06-17 12:52:07 UTC 
Those patches make Compiz and GNOME Shell run for me.  (GNOME Shell has other issues, but at least runs.)
Comment 5 meng 2011-06-17 19:38:29 UTC 
Test the commit 6a574b5b9b186e2 with above two patches, gnome-session works fine when enable compiz.

On gnome-session with compiz, "Hangcheck" in dmesg when open 8-10 "Terminal"
(Applications/System Tools/Terminal).

[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 4034, at 4034], missed IRQ?


Enable semaphores or disable compiz, can fix this "Hangcheck".
