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 Bug 102614.

@Ville, can you correct me if I am wrong.
