Comment 27 for bug 439137

I ran the tests as you requested with all the latest updates and "60-cdrom_id.rules" is the culprit. Whenever its enabled blkid is silent and I can't mount. Note that even with the cdrom_id rules commented out the drive becomes locked after mounting media and then closing the tray with no media in it. However, I can reliably manually blkid, mount, unmount, and eject multiple DVDs and CDs so long as I never close the tray when its empty, because after that it becomes locked and I have to reboot. And of course the physical eject button never works, but I believe that's filed under a different bug.
