After upgrading my box from 8.1 to 8.2 I get the following error while mounting the cdrom

There is a cd inside the cd-tray (suse-8.2), that works.
Some system information: pilchard:~ # cd /dev/ pilchard:/dev # ls -l cdrom lrwxrwxrwx 1 root root 3 Jun 17 21:15 cdrom -> hdc pilchard:/dev # ls -l hdc brw------- 1 richard disk 22, 0 Mar 14 14:07 hdc

I performed the procedure as explained on the link underneath: http://sdb.suse.de/en/sdb/html/aoezcan_cdrom.html, but no changes same superblock error message.

If I'm not mistaken the cdrom treatment in suse-8.1 and 8.2 differ. 8.1 uses ide-scsi while 8.2 has already the plain ide treatment isn't it.
May this be a problem?
pilchard:/etc/sysconfig # grep INITRD * kernel:INITRD_MODULES="ide-scsi"
Richard,
Since you are using ide-scsi emulation you will need to change the link for the /dev/cdrom device as follows (as root):
cd /dev rm cdrom ln -s sr0 cdrom
That got me going :) At this point the mount fails with an error like: "not a valid mount device". After I execute: "modprobe ide-scsi", I can access the cdrom via: mount /media/cdrom :) Where should I put the "modprobe ide-scsi" command, so it is executed during the boot process? Isn't it already specified on the boot prompt command? /boot/grub/menu.lst contains: kernel (hd1,7)/vmlinuz root=/dev/hdb9 hdc=ide-scsi vga=791
The "sr0" device should be the correct one to use. Check your boot log for the cdrom to make sure.
