When it starts - each next DVD is also affected (until reboot). Did you check if unbinding drivers or unloading their modules has the same effect as rebooting? That might help narrowing the area of code to look at. Does it also affect loop-mounted ISOs or is it specific to the CD/DVD drive? As a related test, does it affect CD/DVD drives connected through a different interface? (USB storage, ATA over Ethernet, iSCSI, ...) While at it, please tell us how your CD/DVD drive is connected and which controller it's connected to (relevant dmesg parts). Bruno
