Thanks for continuing to file the gpu lockup bugs. Reviewing all of them (including your manually collected dumps), it is always the same - zero error codes and the WARNING message above. Thinking the latter may be the most relevant bit.
Next step is probably to forward this upstream. Before we do so, since you're able to reproduce this fairly reliably it seems, could you test the current mainline kernel? .debs are available at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc2-precise/ ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Triaged => 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/975083 Title: [sandybridge-gt1] GPU lockup with WARNING: at /build/buildd/linux-3.2.0/drivers/gpu/drm/i915/i915_drv.c:413 __gen6_gt_wait_for_fifo+0x94/0xa0 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975083/+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
