kernel 2.4.0 and audio cd

[Anthony Fox <adf5j@cs.virginia.edu>]

After compiling and running a 2.4.0 kernel, I can no longer play
audio cds.  I can mount data cds just fine, but not audio cds.  If I
try to mount an audio cd I get the following error:

mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems

and the following messages in /var/log/messages:

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 64
isofs_read_super: bread failed, dev=16:00, iso_blknum=16, block=32

I have compiled the iso9660 fs option as a module and have installed
the module in the kernel, if this makes a difference.

Has anyone seen this problem or does anyone know what the problem is
here and how to fix it?

Thanks,
Anthony
