[BlackLight <blacklight86@xxxxxxxxx>]

Same issue on Dell XPS 13 9343.

Running Arch Linux, 4.4.5-1-ARCH, x86_64.

$ pacman -Q | grep xf86-video-intel
xf86-video-intel 1:2.99.917+604+gff0ab2c-1

$ pacman -Q | grep xorg-server
xorg-server 1.18.3-1

Things went better when I upgraded from 1:2.99.917+587+gc186d4d-1 to
1:2.99.917+604+gff0ab2c-1 (flickering was making my laptop just
unusable). But still it happens, although less frequently.

dmesg log lines when the issue occurs:

[ 7780.306704] [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* too many full retries, give up
[ 7824.405766] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
