I'm using the scsi/sata to handle an IDE dvdrw and a SATA dvdrw. I get two
devices named /dev/sr0 and /dev/sr1.

Normally the IDE dvdrw goes to /dev/sr0 and the SATA dvdrw goes to /dev/sr1.
So far so good.

The problem is that about one reboot in twenty, the devices get reversed.
/dev/sr0 is assigned to the SATA drive and sr1 to the IDE drive. This is
a major PITA. Is there any way to fix the assignments?
