<pre>Running Fedora-25 (linux-4.10.14, Mesa-17.0.5, Glamor) on my Ironlake/Arrandale
based Laptop, I get the following messages in syslog along with a flickering
screen:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO
underrun
[drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder B FIFO
underrun
Also, I have seen the system hang at least one time when it actually should
modeswitch.</pre>
