Does it work if you just open the device? For example try
cryptsetup luksOpen /dev/md1 --test-passphrase

Could you please send output with added --debug switch?
It is failing PBKDF2 benchmark here so please try and send output
of these commands as well:
cryptsetup benchmark -h sha256 --debug
cryptsetup benchmark -h sha1 --debug
What distro and version it is?
Do you compile anything (kernel, cryptsetup, library...) yourself?

Key format is not the problem here.
