  You may want to upgrade that kernel; it contains a serious bug in
ext3-code, which bit us several times. Current is e40, by the way.

  Yep, I have found that mount is picky about mounting CDs without the
'ro'-Option, which you have done in your command. You can try either of
these two variants, both should work:

  mount /mnt/cdrom

(this uses the line in /etc/fstab)

  mount -t udf /dev/cdrom /mnt/cdrom -o ro

(telling explicitly to mount read-only, which of course is only sensible
for a CD... :-) )

  HTH
