[root@localhost root]# mount -t iso9660 /dev/cdrom /mnt/cdrom/
ide-scsi: hdd: unsupported command in request queue (0)
end_request: I/O error, dev 16:40 (hdd), sector 64
isofs_read_super: bread failed, dev=16:40, iso_blknum=16, block=32
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
