>Description:
	I have a powermac 4400 that is running -current, which I update
	from time to time (I use it occasionally to test drivers PCI drivers).
	Recent current can't boot however, the machine hangs just after
	the boot loader has loaded the kernel (after the start=0x100000,
	the kernel copyrigth line isn't even printed).
	I narrowed it down to a change in powerpc code between March 13 and
	March 14: A kernel compiled from sources checked out with
	-D2002/03/13 (MET, CVS/Tag is: D2002.03.12.23.00.00) boots fine.
	Updating lib/libkern/arch/powerpc and sys/arch/powerpc (both needs to
	be updated or compile fail) makes the kernel hang as described.
	
>How-To-Repeat:
	Boot a current kernel newer than 2002/03/14 on a powermac 4400
>Fix:
	unknown
