Please test with the following kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
In this newer kernel code is a fix to enlarge unfenced alignments, which appears to be a problem specific to i915/i945. If that kernel makes this lockup bug go away, then we can investigate extracting and backporting it. If not and we can rule out that fix for this issue, upstream (Chris Wilson) will investigate further. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => New ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- 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/715096 Title: [i945gm] GPU lockup (ESR: 0x00000001 IPEHR: 0x02000011) _______________________________________________ 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
