According to Marco d'Itri the /dev/md-* node _is_ removed if the command 'cryptsetup remove $NAME"' is used to bring down a crypto volume (I've not tested this myself). But looking at do_stop() in /lib/cryptsetup/cryptdisks.functions, the only thing cryptsetup seems to do on shutdown is: 'losetup -d /dev/loop$minor' So, maybe this is a cryptsetup issue after all?
