--- Comment #53 from Gustaw Smolarczyk wielkiegie@gmail.com --- At first, I added "|| 1" only to GFX, CP1 and CP2 (I omitted the two DMA conditions). This did NOT fix the pauses.
However, after converting these final two DMA conditions, the pauses are gone. Reverting GFX condition didn't change that.
Also - is there an easy way to check whether the WARN_ON have been fired or not?
