I think I've seen this. Using palcode last modified in Dec 95 and my own
console, NetBSD will come up single user just fine, but the daemons bomb
out with MM faults during the multi-user boot.
I think it's because the EV56 wants some kind of a palcode tweak.
The behavior is a lot like the missing-imb problem. I haven't been able
to work on this since finding it, but hope to get back to it soon. I can
think of a few things that should track it down...
