ibook3 dvd/cdrw problems

[Jon Michaelchuck <michaelchuck@students.wisc.edu>]

Hi,

When I attempt to run eject /dev/cdrom (as root) I get:
eject: unable to eject, last error: Input/output error

My yaboot.conf has line:
append="keyboard_sends_linux_keycodes=1 hdb=ide-scsi"

and lsmod returns:
sr_mod                 17124   0  (unused)
cdrom                  29280   0  [sr_mod]
isofs                  17616   0  (autoclean)

Also, dmesg | grep hdb :
hdb: TOSHIBA DVD-ROM SD-R2212, ATAPI CD/DVD-ROM drive
hdb: Enabling MultiWord DMA 2
ide-scsi: hdb: unsupported command in request queue (0)
end_request: I/O error, dev 03:40 (hdb), sector 64


So, what am I missing here?
