Current hangs at boot

[Martin Husemann <martin%duskware.de@localhost>]

Trying to boot -current on a VS 4000 M96 hangs at:

lk201_decode: error b6

(ignore the audioamd part, it's not commited yet)

I'm using serial console, keyboard is connected and used to work.

Does it ring a bell for anybody?
