Hi, to me this looks a different bug than thye original bug report.
From dmesg I can see like this
3.942231] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared
pch fifo underrun on pch transcoder A
[ 3.942342] [drm:cpt_irq_handler [i915]] *ERROR* PCH transcoder A FIFO
underrun
This issue could be a duplicate of <a class="bz_bug_link
bz_status_NEW "
title="NEW - [CI][HSW only] *ERROR* PCH transcoder A FIFO underrun | *ERROR* uncleared pch fifo underrun on pch transcoder A"
