Hello.  I just got another panic out of the machine this evening.
It looks identical to the last panic, even down to the fault address.
Here's the traceback.  This is I386 NetBSD-1.6.1_RC2, sources as of
February 28, 2003.
	Since this behavior is so frequent, I can't help but think that others
must be seeing it as well.
