Sorry, I guess I should be careful how I use the word "current" on this
mailing list. On the machine in question I am still using 1.1.

No messages are output by the kernel. Only the "mount_cd9660:
Input/Output Error" message. This is the same message that is printed if
a disk is inserted upside down, by the way.

Actually I was sending the message more as information/warning to other
people than to con somebody into fixing it. I've pretty much decided to
return the NEC and keep the Pioneer (which has no problems).

If you'd like me to do some things to it first to gather information for
you, I'd be happy to. I'll have to get -current on a machine with a SCSI
controller first, though (and I can't do that with this particular
machine, since it manages my desktop at work). Is there a recent i386
binary snapshot somewhere?
