cdrom no a valid block device

[root <root vanhat koti>]

I installed new RH7.2 and after that cdrom doesn't work
Reply was "not a valid block device".

I try to use mount -tiso9660 /dev/hdd /dev/cdrom
and
             mount -tiso9660 /dev/hdd /mnt/cdrom
and some variation without any success.
It was only test install.

After that I upgrade my older redhat RH7.0
with this new RH7.2

Firsth I try mount cdrom.
It doesn't work the reply was same.
Next I boot system with older kernell 2.4.1a
and cdrom works again.

It seems to that there is something wrong with that new kernell (2.4.7-10)

Ps. Something good.
Firsth time I got my sound card to working with this RH7.2
It is integrated to motherboard apollo via mvp4.
And managed install kylix_open and working.
