	Sounds to me like the QUANTUM LPS540S 5900 drive is having problems or
the chain is not set up right. I'm not totally familiar with the BSD
system yet, is there any log that will show the sense data on the SCSI
chain right before the errors? Have you double-checked termination,
parity, and other jumper settings?

reasons why it is occasionally nessicary to 
sacrifice a small goat to your SCSI chain.
