System:	NetBSD 1.0_BETA NetBSD 1.0_BETA (LIRYPE) #0: Sat Sep 24 20:39:04 MET DST 1994 hp300

	NetBSD-hp300 on my machine panics right after printing

		real mem = 33546240


		panic: pmap_enter_ptpage: PT page not entered

	After this it drops into the debugger, but the keyboard appears
	to be frozen so it's kind of hard to do further debugging.

	The machine needs a hard reset (pressing the "reset" button)
	to come up properly.  This makes it necessary to be physically
	present to reboot the machine.

	The machine this happens on is identified by the following print-out
	during autoconfig (it is a HP-9000/425):

	Do a "reboot" and watch it happen.
	This is a problem out of my league, sorry...
