I remember it was even mentioned on this list. Anyway, large number of users was bitten by this problem.
It appears that if you do an upgrade as opposed to new installation you end up with wrong link for CD-ROM: /dev/cdrom -> ../cdrdoms/cdrom0 instead of correct one /dev/cdrom -> cdroms/cdrom0 There were so many reports that it can't be user error. I am not sure if it is possible to fix now (I mean, it requires releasing of updated CDs probably that Mandrake seems to avoid). But I hope at least it will be fixed in future versions. -andrej P.S. at least it is worth article on support site. The easy fix is to change links in /lib/dev-state and reboot or just remove contents of /lib/dev-state and reboot.
