There is something strange on your system - either some kernel modules are missing
or something similar. Any other messages in syslog?
According to used mv_cesa module I guess it is some ARM platform, right?
Maybe try to keep LUKS from the picture and check modes works, just
use plain crypt - like this:
echo "password" | cryptsetup create tst /dev/<some dev> -c aes-cbc-plain -s 128
cryptsetup remove tst
Does it fail for all combination of modes?
(Try aes-ecb - it is insecure, but just to test if aes driver works).
If it still fails with "No such file or directory", try some simple device-mapper
target using the same device:
dmsetup create tst --table "0 1000 linear /dev/sda2 0"
dmsetup remove tst
Does this work?
Milan
