This bug is still very much present, even with all the latest updates installed. I just ran into it several times after re-installing my system from scratch and trying again for a moment without the separate videocard. It's even become worse since the system just drops (locks) to a shell (see attached picture I took ) The only way out is a hard reset / power cycle. And after rebooting, Apport doesn't even notice the system has miserably failed.
I tried installing kernel 3.5 from linux-generic-lts-quantal (now at 3.5.0.22.29) and the situation is much better there, even though I did experience one lock-up as well. This lock-up was a bit different though, since the system didn't drop to a shell and I could still move the mouse cursor. Still had to hard reset my machine though. What can I do to get this issue sorted out? ** Attachment added: "picture of my screen when the lock-up happened" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975083/+attachment/3487791/+files/20130118%20i915%20lock-up.jpg -- 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/linux/+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
