--- Comment #30 from rockorequin at hotmail.com ---
I just saw the eDP display flicker again, so I think these patch don't
completely resolve the problem. The nearest relevant message in the syslog is:

Oct 14 16:04:07 xps15-9550 kernel: [46013.541604]
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun

Are there other patches I could try against 4.8.1? The drm-intel-nightly kernel
is behaving quite well.
