I just had a GPU lockup again, and apport indicated it was a duplicate of this one. The superficial symptoms were different; different error message when trying to restart compiz, and unlike previously, the system didn't go into an unresponsive high-load state. But that may have been a secondary symptom.
Attaching the new i915_error_state, in case it's useful. ** Attachment added: "i915_error_state.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1119793/+attachment/3572390/+files/i915_error_state.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1119793 Title: [arrandale mesa] GPU lockup IPEHR: 0x02000000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1119793/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
