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 Desktop Packages, 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]() Status in “linux” package in Ubuntu: Expired Status in “xserver-xorg-video-intel” package in Ubuntu: Expired Bug description: Might be similar to bug 902787, but I do have composite enabled so therefore filing a new bug. I just installed 12.04 beta 2 today (fresh install), updated it and after a reboot I was just working with SC to re-install my apps using the nifty 'Sync Between Computers' option, when suddenly SC exited and the entire UI froze (however, the mouse cursor kept on working). Could not even switch back to terminal using CTRL-Alt-F1. Only a hard reset remained. Fortunately, apport has been much improved an promptly asked me to file this bug. So here you go.
