Bug Description
Twice in the past week, I've had an i915 GPU lockup with the maverick kernel. First with 2.6.35-16, now this latest with 2.6.35-20:
Sep 8 17:25:43 dario kernel: [440048.562567] [drm:i915_
Sep 8 17:25:43 dario kernel: [440048.562706] [drm:i915_
This manifests as the X screen freezing for a few seconds, then going black, then X restarting in failsafe mode. Console works fine, but drm doesn't come back without a reboot.
I've noticed a rough but not definite correlation with toggling the video output selections and/or the lid status.

Same happens here on Kubuntu 10.10 almost every day. Kwin effects are enabled.
I'll attach a log sample from yesterday (egrep -i "i915|intel" kern.log | grep "Nov 23")

Unfortunately Xorg.log was rotated out but I'll upload one from today anyway.
Let me know what else do you need.
