I'll be honest, I don't know that part of the code well. I assume that the
resetting of all busses occured above where you moved the code to?
i.e. we reset all busses, sleep once, then probe all busses? One question,
won't that make the per-bus check, (chan->chan_flags &
SCSIPI_CHAN_NOSETTLE) == 0, useless?
