eject: '/dev/sr0' is not a mount point
eject: '/dev/sr0' is not a multipartition device
eject: trying to eject '/dev/sr0' using CD-ROM eject command
eject: CD-ROM eject command succeeded

$ sudo umount /dev/cdrom
umount: /dev/cdrom: not mounted

$ sudo eject /dev/cdrom -v
eject: device name is '/dev/cdrom'

Meu problema é semelhante no Ubuntu 14.04. Se eu usar "ejetar" para remover um CD de dados e fechar a bandeja vazia, o botão na bandeja para de funcionar. O comando "sudo eject -v" não consegue abrir a bandeja. Eu não acredito que seja uma falha de hardware, pois depois de um reinício, o botão funciona novamente.
