although not much else is happening.

virtual address caches are touchy when it comes time to flush them and
change mappings ...

in particulsr, you have to
	flush()
	change mappings
	invalidate TLBs

in careful order. Note that PACs are not nearly so picky.

anyway ... where I'm at is init code is in memory, I'm trying to switch to
it, at some point mmuswitch is called again, then again, and that third
time ... no joy, the system dies.


but it's closer .
