--- Comment #5 from Norbert Varzariu <loomsen at gmail.com> ---
OK, so what I found is: no hangs, but frequent

[68176.532833] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe B FIFO underrun

errors in my syslog. Usually this leads to the screen being blacked out for a
split second, before it is redrawn. The system itself is rather stable, I
didn't have a hang up anymore, the error state is clean also. 
Only these occasional blackouts.
