I had a similar problem .... I had a CD drive that work happily under a kernel
built by RedHat BUT not my me :(
Through much playing (I spent 3 hours in a config;build;install;boot;testi
loop)  Eventually I worked out which kernel seetings I'd left out and all was
fine.  I seem to recall that it was:
----
Block Devices:
Generic PCI IDE chipset support
 Generic PCI bus-master DMA support   
----

Try that .... if that fails then I can always send you my .config for
2.2.18pre17  and you can try that.

In Bash you can:
# mount /mnt/cdrom 2>/tmp/mount.out
This will make stderr end up in the file /tmp/mount.out
# mount /mnt/cdrom >/tmp/mount.out 2>&1
This will make stdout and stderr end up in the file /tmp/mount.out
# mount /mnt/cdrom >/tmp/mount.out 2>/tmp/mount.err
This will make stdout goto /tmp/mount.out and stderr end up in the file 
/tmp/mount.err
in Csh:
mount /mnt/cdrom >& /tmp/mount.out
Send both stdeer and out to /tmp/mount.out
(mount /mnt/cdrom >/tmp/mount.out) >& /tmp/mount.err
This will make stdout goto /tmp/mount.out and stderr end up in the file 
/tmp/mount.err

Also with kernel errors of that nature you'll find that they end up in
/var/log/messages (or similar check /etc/syslog.conf for the exact location)


Yours Tony.
