There's a couple of old patches floating around still that you might want
to apply.  I have reproduced them below.

as129 handles the situation where a command error causes us to do a device
reset, but the SCSI layer times out and aborts the command during the
reset delay.  It clears a flag that otherwise will prevent us from sending
the clear-halt messages following the reset.

as141 is the DMA buffer alignment patch.  You asked me to remind you about
it eventually.  There shouldn't be any harm at all in applying it without
waiting for the corresponding SCSI part of the patch to be applied.
Without that other part, this will essentially do nothing.
