Is this a termination problem?

Hi!

I'm having trouble with a remote server. Can someone tell if the message below comes from a scsi termination problem?

Apr 12 02:48:27 backup kernel: (scsi1:0:3:-1) Unexpected busfree, LASTPHASE = 0xa0, SEQADDR = 0x162
Apr 12 02:48:28 backup kernel: st0: Error with sense data: Current st09:00: sns = 70  5
Apr 12 02:48:28 backup kernel: ASC=20 ASCQ= 0
Apr 12 02:48:28 backup kernel: Raw sense data:0x70 0x00 0x05 0x00 0x00 0x00 0x00 0x0e 0x00 0x00 0x00 0x00 0x20 0x00 0x00 0x00 0x2c 0x01 0x00 0x00 0x00 0x00

This is with the old aic7xxx driver, but with the newer (Adaptec) aic7xxx driver I get similar messages:

Apr 11 08:59:40 backup kernel: (scsi1:A:3:0): Unexpected busfree in Message-out phase
