>Description:
	I got this on a dual P3 system while running 2 pkgsrc bulk buidl,
	and a gunzip of a large file:
panic: kernel debugging assertion "l->l_cpu != curcpu()" failed: file "/local/pop1/bouyer/netbsd-2/src/sys/uvm/uvm_glue.c", line 605

I have a kernel core dump

>How-To-Repeat:
	Run intensive CPU tasks + intensive file I/O on a dual-CPU system ?

	unknown
