Sigh, me either. I've been doing most of my stuff on XScale.

I looked at the problem just now... it's not just the undefined insn
trap that loses. Looks like all traps are losing.
Off the top of my head, I'm thinking it could be:
* Cache stuff (not properly cleaning the vector page?)
* Vector page re-org
CATS kernels are working, though, right?
Anyway, I'll poke around at it tonight and see if I can't track it down.
