Why are you turning off disconnection??? That will kill your performance.

This is probably a termination problem. Search for STPWEN in
i386/scsi/aic7xxx.c and remove the two occurances of this. The
diff should look like what I include below. I have a solution for
setting this dynamically that will be going into current tonight and
into stable before the 2.1.6 release, but first let me know if this
helps your problem. It may also be some other problem in the driver
that has been fixed already, so if this doesn't work, I'll send you
the new driver ported back to 2.1.5R.
