Thanks to John Baldwin's patch for hptmv I'm now back at the stage
where the machine hangs as during initialisation of the CPU's.

I've got WITNESS, INVARIANTS, KDB and DDB installed but I cant
break to the debugger as it seems to be totally wedged.

If I break to the debugger earlier and continue it doesnt hang
any ideas on how to proceed would be greatfully appreciated.
