<pre>I'm pretty sure that this is what I am experiencing on a MacBook Pro 12,1.
Screen randomly goes black and comes back again. Afterwards I see
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun
or
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO
underrun
or both in dmesg.
Graphics is Intel® Iris 6100 (Broadwell GT3)
I'm on Ubuntu 16.04 with default kernel. Linux JMK-MBP 4.4.0-34-generic
