I never used encrypted cdroms. But first check if the cdrom is seen at all. You can check in k3b without mounting it.
CDROM appears as hdc or sr0? The link you provided is down at the moment. LOOP_SET_STATUS: doesn't appear in my kernel 2.6.24-gentoo-r3. So you are probably right that it's 2.6.23. Check this: grep LOOP /usr/src/linux/.config CONFIG_BLK_DEV_LOOP=y CONFIG_BLK_DEV_CRYPTOLOOP=y and see if you have cryptology enabled. I believe that you have a mistake in /dev/loop/ . Shouldn't be /dev/sr0? Take a look at my setup: ls /dev/cdr* /dev/cdrom /dev/cdrw ls -l /dev/loop total 0 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 0 -> ../loop0 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 1 -> ../loop1 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 2 -> ../loop2 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 3 -> ../loop3 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 4 -> ../loop4 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 5 -> ../loop5 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 6 -> ../loop6 lrwxrwxrwx 1 root root 8 2008-10-19 21:42 7 -> ../loop7 ls -l /dev/sr0 brw-rw---- 1 root cdrom 11, 0 2008-10-19 21:43 /dev/sr0 how is your cdrom configured? sata, ide?
