So obviously the hardware works.

I've missed the beginning of this thread so you may have already
posted this, but it sounds like you have a broken grant chain
(i.e. the box is not in a valid configuration).

Can you post the config (which board is in which slot)?

SHOW DEVICE at the console might also be useful (in the
non-function config).
