SCSI bus errors



Hello all,

I recently had SCSI bus errors that forced a reboot on my home server. It's 
a Poweredge 2200 w/ the AIC-7880 SCSI chipset onboard. I've never had 
problems before, and it just happened suddenly. Below are the first 150 
lines from /var/log/messages where the problem first occurred. Any ideas on 
what happened? This is a used system I got cheap. Could the drives be going 
bad?

Here's the info on my SCSI setup.
