cannot mount cdrom

Hi
I run debian 2.4.21-xfs
I decided to try a newer kernel image: 2.4.22-1-686
everything seems to work fine when I boot with the older image, but I'm having problems with the newer one.

I'll just cover one problem for now.
I cannot mount my cdrom...and yes I was root, and yes I have mountpoints defined.
I could guess that some modules didnt load, but thats just a guess, I dont know enough to make even an educated guess.
here's the commands I tried and the output I got:

bash-2.05b# who
root tty1 Dec 10 14:47

bash-2.05b# mount /cdrom
mount: /dev/cdrom is not a valid block device

bash-2.05b# mount -t iso9660 /dev/cdrom /cdrom
mount: /dev/cdrom is not a valid block device

bash-2.05b# ls /
bin cdrom1 floppy initrd.img lost+found morphix sbin var
boot dev home java miniroot proc tmp vmlinuz
cdrom etc initrd lib mnt root usr

bash-2.05b# ls -al /dev/cdrom
lrwxrwxrwx 1 root root 9 Oct 10 21:20 /dev/cdrom -> /dev/scd0

bash-2.05b# ls -al /dev/scd0
brw-rw---- 1 root cdrom 11, 0 May 31 2001 /dev/scd0

bash-2.05b# mount /dev/scd0 /cdrom
mount: /dev/scd0 is not a valid block device

bash-2.05b# mount -t iso9660 /dev/scd0 /cdrom
mount: /dev/scd0 is not a valid block device

If you need more info to help, just ask.

Do a lsmod and see if these are loaded/

Code:

ide-scsi               11008   0 
scsi_mod              107596   1  [ide-scsi]
ide-cd                 32256   0

If not, check and see if you are passing hd<X>=ide-scsi to the kernel through your boot loader.

........ and after you've done that check

dmesg | less

the block device could be ??

/dev/sr0

(0=zero)
