--- Comment #14 from rockorequin at hotmail.com ---
I just saw my eDP screen flicker even though I'm using my patched kernel
(patched with https://patchwork.freedesktop.org/patch/113642/). Around the same
time, this appeared in the syslog:

Oct  6 11:26:50 xps15-9550 kernel: [ 6296.557426]
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun

So the problem isn't completely resolved by the patch, although its frequency
is certainly reduced.
