Xorg on haswell freezes on high load, restart attempts fail

[Andreas Pokorny]

Mouse cursor was still updated during the freeze. The freeze occurred during a kernel build with 8 threads and an opengl game running on a different desktop but continuously rendering and claiming the cpu.

Status changed to 'Confirmed' because the bug affects multiple users.

[Chris Wilson (ickle)]

First an EBUSY when changing modes, then the GPU stops flipping. The stacktrace is inconsequential. However nothing is reported in the dmesg for the failure, which makes me think that it is a stuck pageflip.

[Andreas Pokorny (andreas-pokorny)]

Yes the stack trace is from the lightdm restart attempt, when I tried to manually resolve the freeze.

[Chris Wilson (ickle)]

http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/ should prevent the lockup
