After upgrading kernel I lost my CDROM
I have been running a version of woody from Feb 28, 2002 on a 686
machine using the 2.2.19 kernel that was installed from a potato cdrom
set and then the software was updated from another cdrom set to
woody. Everything was working fine for many days, but xcdroast
complained about cdrecord not working since it needed a 2.4 kernel.
So finally tonight I did an apt-get install kernel-2.4.17-686 and that
went fine and is what I'm using now. HOWEVER, when I try to access the
cdrom drive I get the following in dmesg:

My lilo.conf has append="hdd=ide-scsi" in it.
My question is: what did I hose in updating the kernel since it is
most unhappy with hdc??
Thanks for any advice.
