--- Comment #1 from Daniel Vetter <daniel at ffwll.ch> ---
Can you please test each output mode individually and correlate which one is
responsible for this? Or does this only happen occasionally?

Note that fifo underruns depend upon the platform, memory chips and output
configuration, so it's likely that we need to split this bug up into a lot of
different reports.
