[Bug 1555158] Re: Screen flickering in kernel > 4.4.0-8 on XPS 9550
Same issue here. I have the Dell XPS 15 1080p with i7-6700HQ running on
kernel 4.4.0-18. There's an occasional completely black frame. The
flickering seems to start after
"[drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe A
FIFO underrun" appears in the system log.
The same issue seems to occur on the latest Dell XPS 13 as well:
