Hi,

mounting a CD-Rom results in the following error message:
| root#  mount -t cd9660 -o ro /dev/cd0a /mnt
| mount_cd9660: /dev/cd0a on /mnt: Input/output error

/var/log/messages contains this message:
| root# tail -1 /var/log/messages
| Mar 11 14:52:35 gate /netbsd: cd0(siop0:0:5:0): medium error, data =3D 00=
 00 00 00 57 00 00 00 00 00

Writing a CD-R fails, too.
Cdrecord says:
| root# cdrecord -scanbus

Hardware in question is:
| root# scsictl cd0 identify

| root# dmesg | grep scsi

ds for devices to settle...
| cd0 at scsibus0 target 5 lun 0: <YAMAHA, CRW4416S, 1.0j> SCSI2 5/cdrom re=
movable

System:
| root# uname -mprs=20
| NetBSD 1.6.1 i386 i386

What does this exactly mean? Broken hardware?
