Just started using tape devices w/this machine.
After doing a mt status, then mt erase, then mt erase
here's what got logged.

machine just dies. No panic, just stop responding. Will ping, but
no telnet. Can switch virtual terms ok....went into kernel debugger
and it was doing scsi operations. Mt was donig wmesg was scsicmd--
also there were time outs for the devices. I put it in kernel
debugger, did about 5-20 nexts and it got Page-Fault 12 supervisor
read.
I have done this about 3 times in a row, is easy to replicate.
Here's dmesg
