I get my system booted up to the busybox prompt via nfs root file system.
After this most commands do nothing at all (as described from andrew may
"405GP booting"), and the system hangs pretty soon :-(.

I would think that the walnut port is behaving this way too, am I right?

If you are interrested, please take a look at the bootup snapshop of our
board:
