[gentoo-user] empty cdrom drive is busy or mounted

[Helmut Jarausch]

Hi,

I have a very strange effect on my Gentoo system.
First, I've check that /dev/sr0 points to the correct device (from  
dmesg)

For an empty drive  I get

1 # mount /dev/sr0 /cdrom
mount: /cdrom: /dev/sr0 already mounted or mount point busy.

2 # lsof /dev/sr0

3 # umount /dev/sr0
umount: /dev/sr0: not mounted.


Does anybody know what's going on here?

Many thanks for a hint.

P.S. I have checked this with two physically different drives.
