SubjectRe: Any SMP people out there with SCSI CD ROMs?
I have a couple of SCSI CDROM machines, but not SMP.  If the problem
is SMP related, I might could steal a SCSI CD for a bit and do some
testing.  If it is non-SMP I can test easily...  I have machines with
SCSI CD's, SCSI cd writers, SCSI tapes (5 and 24 gig tapes on the same
machine) and so forth.

Let me know if I can help here...  I'm running a quad P6/200 that is
rock steady on 2.1.105 so far, and was up on 2.1.103 for 14 days...
