System: NetBSD cerumen.trpz.com 1.6ZD NetBSD 1.6ZD (NATES) #1: Mon Nov 10 12:58:16 PST 2003 djg@nates.trpz.com:/home/djg/src/NetBSD/usr/src/sys/arch/i386/compile/NATES i386
Architecture: powerpc
Machine: powerpc
>Description:
	The recursion test at the head of pmap_pvo_enter() is
	done outside of the protection of "pmap_interrupts_off()"
	and hence any interrupt occuring during the test could cause
	the test to fail.
>How-To-Repeat:
	Just have a manager or customer try something trival that
	you swear has been running fine for years. :-)
>Fix:
	move the test below "msr = pmap_interrupts_off();"
