>Description:
When audio CD is into CDROM tracks aren't reflected correctly by ls /dev/acd0*.
Right after reboot only /dev/acd0 shows up when audio CD is in.
But after I do 'mount -t cd9660 /dev/acd0 /cdrom', mount errors out but all tracks appear in /dev/acd0 (t01, t02...)
When I remove audio CD 'ls /dev/acd0*' still reflects tracks from the previous CD, same after I insert a new audio CD. Tracks reread again only after I attempt the mount command.

So the problem is that tracks aren't read by atapi driver automatically. Also they aren't cleared when CD is removed.

This isn't reflected in Handbook, so people who just follow the Handbook will fail miserably.
