/dev/cdrom is not a valid block device

From Bugzilla Helper:
User-Agent: Mozilla/4.72 [en] (Win95; U)
Description of problem:
Upgraded working 7.1 install on Toshiba laptop. After upgrade, cdrom not
recognized. Message above received on attempt to mount. /etc/fstab had
valid entry for cdrom.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Download iso images, verity with md5sum.
2.Prepare boot image floppy, as machine will not boot from CDRom
3.Choose upgrade option during installation.
Actual Results: Could not access CDROM with standard mount command
Expected Results: Automount, right-click mount option on gnome desktop,
Workaround/bug: Problem remedied by logging is as root, typing insmod
cdrom at command prompt. cdrom.o is present in module library, but not
being loaded. Verified upgrade/workaround twice.
Alternative workaround: Instead of upgrade choice during install, choose
laptop install option. Keep existing partitions and mount points, no
reformatting. Reformat and mount swap partition. Proceed throught
install normally. Upon reboot, cdrom working normally, as it was in 7.1.
It seems that during an upgrade the kernel modules map doesn't get written
properly in all cases; "depmod -ae" as root fixes that, or an upgrade to the
security errata kernel.
Just looked for above referenced "security errata kernel" on www.redhat.com and
unclear which package you refer to? Please advise. Thanks.
is what I ment...
The bug that cuases the problem with CD-ROMs will be fixed in a future installer
