--- Comment #5 from Jesse Barnes <jbarnes at virtuousgeek.org> ---
Yeah this does sound like a FIFO issue somewhere.  And the display tends to get
really stuck when that happens, which matches your "restart X" not working
experience.

Can you try a current kernel from drm-intel-nightly and see if the issue
happens?

Can you force it to happen by putting a load on the system, especially a memory
intensive one like lots of drawing and CPU activity in the background (some
kind of number crunching maybe)?
