i cannot imagine that this is related to the filesystem at all. dm-crypt doesn't mind the content of the encrypted device. do you still remember the cryptsetup version in use when you formated the encrypted device? changes to the iteration time in PBKDF2 password processing might be the reason here. milan, what do you think about this issue? greetings, jonas
