Regarding the fifo underruns, yes I agree. Those two lines were accidently
copied as part of the traces.
As for the vblank timeout issue, I will be willing to test any potential
patches. Those particular vblank timeout issues (vblank wait on pipe B timed
out) have only appeared in the RCs for linux-3.18
