Ok - is there a good reason for not using spl calls to block the
interrupt until the tsleep(), or is it just an oversight? I guess
maybe you are trying to avoid the delay associated with deferring
the interrupt, but it must open up a number of races, especially
if the ATA interrupt line is shared with something else.
