[wplug] CDROM no long reads Audio CD's

[Bill]

Anyone know why this might happen?  I can mount data cd's fine but audio
cd's get the following error:

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

This is the corresponding dmesg entry:

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