 I don't know where the error lies, but I created two loop devices loop0
 and loop1, added them to a new RAID 1 md0 device, and ran cryptsetup on
 the resulting md0 successfully.

 bee:~# dmsetup  ls
 ...
 crypt0  (253, 6)

 bee:~# dmsetup table crypt0
 0 65408 crypt aes-cbc-plain

 bee:~# mdadm --detail /dev/md0
 ...
