Public bug reported:
Hi,
since upgrading to Yakety I have been experiencing occasional loss of
display (black screen) lasting for usually 2 seconds (although yesterday
(23rd Oct) the display did not return).
Today, I found the following message in my syslog shortly after the
incident.
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun
I have experienced this issue on my installed OS and also with a live cd.
Issue has occurred with both HDMI & DP connection to monitor.
Hardware is Intel i5-6600 with HD Graphics 530 (Skylake GT2)
Display is 27" 2560x1440.
