The DMA timeout itself could be all sorts of things - crap driver, crap
hardware, PCI bus contention, noise, problem disk, phase of the moon.

If you've got a nice repeatable problem please try using the libata
driver. That handles the error paths differently and doesn't try a FIFO
drain which might matter in this case I guess.
