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: Confirmed => 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/718021 Title: [i946gz] GPU lockup f3077a7e (ESR: 0x00000001 IPEHR: 0x87000000) - WARNING: at /build/buildd/linux-2.6.35/mm/page_alloc.c:1986 __alloc_pages_slowpath+0x36d/0x4b0() _______________________________________________ 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
