Well, is this general a show stopper? In my opinion that should
not break the state when powered up, but...

ok.
... sometimes when the third or fourth interrupt is processed, the
register dumps are totally freaked up:

is that a timing problem or BE<->LE stuff?
I think not hardware related because the 16bit register look still ok...
