--- Comment #5 from Mika Kahola <mika.kahola at intel.com> ---
When the test fails i.e. reading of the CRC debugfs blocks for more than 5
seconds these errors pop up

[  503.298054] [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR*
uncleared fifo underrun on pipe B
[  503.298063] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe B FIFO underrun
