JT,

As you probably have seen, there's not much from Google.  The
ipb_dma_err text is probably coming from the v4l or cx88 driver(s), as
that seems to be where the text is sourced.

I guess that cx88 is your frame buffer chipset.  I don't have the source
for the v4l modules handy, but for grins, what does cat /proc/interrupts
give you?  Shooting the dark here, maybe its an interrupt conflict.  You
could try moving your frame buffer card to another slot.

Does MythTV work in this state?
