The following reply was made to PR kern/4851; it has been noted by GNATS. From: "Justin T.

Set the termination manually in SCSI-Select instead of relying on auto-termination. You should also upgrade to a later revision of the driver (as in 2.2-stable) since there have been many bug fixes since 2.2.2R was released. -- Justin T.
