I got different ones on rc5 :)

[    0.970103] [drm:intel_set_pch_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder A
[    0.970107] [drm:intel_pch_fifo_underrun_irq_handler] *ERROR* PCH transcoder A FIFO underrun

and I'm wondering whether those can be simply shut up or we can actually
do something about them...

Thanks.
