[lug] CDROM mounting woe

[qqq1one @yahoo.com]

I don't know if the following problem is related to
the CDROM install failures I mentioned in my previous
post
(http://archive.lug.boulder.co.us/bymonth/2001.10/msg00968.html),
but perhaps it is, hence the reference.

I've done 3-4 fresh installs of RH7.2, and haven't
been able to mount the CDROM with any of them.  The
CDROM still works with my 6.2 hard drive.  Here's the
error I get:

# mount /dev/cdrom
mount: /dev/cdrom is not a valid block device


Here's what fstab has (the floppy works):

# cat /etc/fstab
<snip>
/dev/cdrom              /mnt/cdrom             
iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0                /mnt/floppy             auto  
 noauto,owner,kudzu 0 0


Here's what the devices look like:

# ls -al /dev/cdrom
lrwxrwxrwx    1 root     root            8 Oct 29
23:28 /dev/cdrom -> /dev/hdd
# 
# ls -al /dev/hdd
brw-------    1 install  disk      22,  64 Aug 30
14:30 /dev/hdd


Here's where the problem seems to be first detected:

# cat /var/log/messages

startup stuff plus more failed attempts to load

Here's what the drivers/ide and drivers/block
directories look like (I noticed that the ide-cd
driver is now in the ide directory instead of in the
block directory like it was with RH6.2):

Here's what happens if I try to load the same cd
driver module that works in RH6.2:

# /sbin/insmod
/lib/modules/2.4.7-10/kernel/drivers/ide/ide-cd.o
ide/ide-cd.o: unresolved symbol

I searched on "insmod ide-cd failed" at RedHat.com and
none of the 4 results it came back with were for this
problem.  I also tried variations on that search, but
still couldn't find the same problem addressed.  Does
anyone have an idea how to fix this problem?
