I get the same.  (well thought it was code 2)
Mike Smith and I have talked about it and couldn't immediately think of
which commit could have broken the loader.

At the loader 10 sec count down, do:

    unload
    load kernel.old
    boot

This works for me.  Seems unloading and reloading a kernel "fixes" the
problem.  Sometimes I am even able to load "kernel" after the unload and
have it boot.
