Some rough guesses to get you started:
1. Keyboard layout specific passphrase? Do you use a non-american
keyboard layout? Maybe it has not been loaded at the time you enter the
2. Check that all necessary components (hash algorithm, block cipher,
encryption algorithm) are compiled into the new kernel.
Hope this helps,
