I keep experiencing this issue, using Ubuntu 17.10, an Intel Core i3-5005U (with Intel HD 5500). It appears most often when a new notification comes in (Slack/Spotify) and the lockscreen is visible.

From dmesg:
[Fri Feb 23 13:51:50 2018] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

$ uname -a
