I notice your DMA buffer length is very short, which would require
very frequency interrupts to service, right?   Can you increase your
DMA buffer length by increasing the period size?  Maybe that would
help reduce the likelyhood of a failure.  Although it would be good to
be able to recover from a failure gracefully.
