I had a strange problem where the system kept crashing while trying to
access my SCSI bus, and it was a bent pin on one of the connectors. I
know this is obvious but have you checked for this / unplugged + plugged
them all? I have also heard that some Adaptec cards can be a little fussy
about impedances and termination as well - how are you terminating the
buses: using jumpers on the devices, or plug in terminators?
If you are worried about fsck's then you might try booting off a boot
disk, and then running cdparanoia with the data output redirected to
/dev/null (there won't be enough space for the output file otherwise).
Also - what CD device are you using? Have you tried using the other CD
device and does it still crash using this?
