Kernel hang with Adaptec 29160 and HP 6*40GB Surestore Autoloader

[Buchan Milne]

Hi,

I am trying to set up backups on our Linux Mandrake 8.0 fileserver. The 
machine is a 500 Celeron on a Gigabyte 6BXE mb, 1 HPT370 ATA100 
controller, 3 IBM 45 GXPs, 1 Fujistsu 6.4GB drive, 1 Adaptec 29160 SCSI 
controller which has only the HP 6*40GB autolader. Using RieserFS on all 
partitions except /boot. Was initially running kernel 2.4.3-20mdk, but 
currently using 2.4.7-8mdk. aic7xxx driver in the current kernel is 
6.1.13. 29160 is running BIOS version 3.1.10 (latest), Gigabyte 6BXE is 
also running latest BIOS version (F2e). Everything on the machine is 
stock Mandrake, except samba -2.2.1a and the 2.4.7-8mdk kernel.

Running:

# mt -f /dev/st0 status

when a tape is loaded hangs the machine solid, with only the following 
information on the screen:

(scsi0:A:3): parity error detected in Data-in phase SEQADDR(0x1a8) 
SCSIRATE(0x95)

If I use mtx (recompiled from Redhat SRPM) as follows:

# mtx -f /dev/sg0 status

I get the same error (not necesarrily the first time, but definitely the 
second time).

Is this error fixed in the latest aic7xxx driver, or should I be looking 
elsewhere for the problem. Note that currently the SCSI cable is not 
actively terminated, if that makes a difference.

Regards,
Buchan

P.S. Tomorrow is a public holiday here, and I am taking a long weekend, 
so I will get back into this on Tuesday, but any replies are welcome ...
