>Description:
	Kernel hangs at bootup after printing real memory=xxx line. I added
	printf's to machdep.c and discoved the hang is in pmap_enter while 
	allocating the 289'th buffer. If machdep is forced to allocate only
	288 buffers the kernel hangs after the printing:
	avail mem=xxx
	using 288 buffers containing xx bytes of memory.
>How-To-Repeat:
	Boot kernel on RiscPC.
>Fix:
	No idea.
