It was me who posted this previous message. :)
I don't think it is drive dependent. But it may have something to do with SCSI since it works for you with IDE and oopses with SCSI. I just reproduced the oops with a hdc: HL-DT-ST RW/DVD GCC-4120B, ATAPI CD/DVD-ROM drive IDE drive running via ide-scsi. Same oops again, see below. Yes I know with NVdriver, but the oops is the same with and without. Now the disc isn't mounted, the drive door is locked and 'eject /dev/cdrom' gives
eject: CDROMEJECT ioctl failed for `/dev/scsi/host1/bus0/target0/lun0/cd': Device or resource busy
