    The five CRC in a row is what causes the DMA->PIO changedown. That
    implies there is a real bug in the error handling locking, or in
    the driver handling of that.

    Can you throw some printks into the ide code and see what kind of
    a death you get when it tries to change back to PIO.

    As to the cable stuff, I'll take a look at it in time, but both
    need fixing
