Howdy!

	Supped todays stuff hoping to get NFS changes and ran into a
	little problem, mainly the kernel wouldn't boot. Dies shortly
	into boot with:

	Rebuilt everything last week from the 11/25/96 sup. Today I ran make
	includes to catch recent .h changes and then config'd and
	make depend then make the kernel, config dir was from scratch so
	no remnants would be around. Tried to boot it and KA-BOOM,
	the above. Stack trace showed:

	Hardware is a crusty old 1+ SPARC with 36M of memory and 1 drive.

	Any ideas what might be wrong? Did the param.h changes goof something
	up? Any other major changes in the past week that would blow an old
	crusty sun4c out of the water in the pmegs dept.?
