Hello,
When running the 2.6.39-rc7, I've observed a problem on my laptop (DELL XPS15) which uses the i915 driver. Frequently, when moving the mouse over, the cursor does only trigger the modification on the desktop after a few seconds (like icons highligthing). When this occurs, the following message appear in the kernel log at the moment when the waited action occurs:
[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 905, at 905], missed IRQ?
Switching back to 2.6.39-rc6 fixes the issue.
It runs gnome 3 which uses glx to add some effect. Maybe this is linked. When using the simple twm window manager, the problem does not seem to occur.

Try booting the latest kernel with "i915.semaphores=1" and it should be fixed, at least for my SNB hardware. When I had it auto-bisected it came down to this commit 087fbc9962e10a65fb0b542ecfc116ebf6cf1735 that disabled semaphores.

I confirm that it is working fine when enabling semaphore. Thanks a lot for the workaround, it is a pleasure to have a real laptop again ;)
Good luck for the bisect.
