consistent kernel panics in panther

Recommended Posts

I'm getting constant kernel panics using Retrospect Server 5.1.175 + Driver Update 4.2.105 + SCSI Update (10/3/2003) on Mac OS X 10.3.1 with an ATTO ExpressPCI PSCd. Backups seem to run fine for short periods of time before getting a kernel panic. This setup worked fine (without the Driver and SCSI updates) under Mac OS X 10.2.8. Here is the panic.log:

Kernel version:

Any ideas? I'm most likely going to revert back to Mac OS X 10.2.8 later today or tomorrow as this is certainly a Retrospect+Panther problem...
