Could you please give me some hint how the /dev/dm- nodes are created ?
I will try to reproduce it on my hardware.

Thanks for the report.

I created them with 'cryptsetup luksFormat ...', IIRC. When I run 'cryptsetup luksDump' I get:

Version: 1
Cipher name: aes
Cipher mode: xts-plain64
Hash spec: sha256
Payload offset: 4096
MK bits: 256
MK digest: <STUFF>
MK salt: <STUFF>
MK iterations: 400000
UUID: 81a8d12e-9309-4317-b447-ab3c86e2f7ea

Key Slot 0: ENABLED
Iterations: 3200000
Salt: <STUFF>
Key material offset: 8
AF stripes: 4000

and this is the contents of my /etc/crypttab:

# <name> <device> <password> <options>
crypted-sdb /dev/sdb1 /etc/cryptfs.key
crypted-sdc /dev/sdc1 /etc/cryptfs.key
crypted-sdd /dev/sdd1 /etc/cryptfs.key
crypted-sde /dev/sde1 /etc/cryptfs.key

Oh, I don't use cryptsetup before, let me try ... Thanks for the hint :-)
