aic7xxx driver problem

Hello,

I have recently been having problems with the aic7xxx driver on two of my 
Redhat machines, both used for tape backups.  We use Veritas Netbackup, 
and have been seen strange media/tape errors, with the following 
corresponding errors in the messages log (these are just some examples 
that have accumulated over the past few weeks).

kernel: st1: Error with sense data: Info fld=0x0, Current st09:01: sense 
key Medium Error
kernel: st1: Error with sense data: Current st09:01: sense key Aborted 
Command
kernel: st1: Error on write filemark.

I tried writing and reading some tars using the tape drives, and I see 
this in messages when I attempt to rewind a tape (using the mt -f rewind 
command) on the drives.  This particular machine is running 2.1 AS, but it 
happens with 3.0 ES as well.

Any help would be greatly appreciated!
Thanks.
