on my home box (2.0.5, PCI NCR), I have SCSI CD and HD installed, and when
I do 'eject' in cdplay, the machine reboots!! (in single-user, without
swapping, I was able to see an error from driver, after that it resets
the devices (effectively disabling them), and so all disk accesses 
give me 'I/O error'.  In multi-user, I have catched a fast scrolling 
horde of swapper messages about errors on swap device (no doubt it rebooted
shortly).

I would upgrade to 2.1 (or may be would just get a driver from 2.1 first and
see whether the problem would persist).

dmesg output follows:
