System: NetBSD frotz 1.4P NetBSD 1.4P (FROTZ) #2: Sat Jan  1 11:59:59 EST 2000 danw@frotz:/usr/src/sys/arch/macppc/compile/FROTZ macppc

>Description:
	Certain swapctl failures can cause the machine to panic.
>How-To-Repeat:
	Try to enable swapping to a partition that isn't listed as a swap
	partition in the disk label
>Fix:
	I think the fix is to revert revision 1.29 of uvm_swap.c: The
	comment in sys_swapctl at line 655 says vp should already be
	locked.
