System: NetBSD v120 4.99.40 NetBSD 4.99.40 (GENERIC) #0: Wed Dec  5 01:12:11 PST 2007  builds@wb25:/home/builds/ab/HEAD/sparc64/200712040002Z-obj/home/builds/ab/HEAD/src/sys/arch/sparc64/compile/GENERIC sparc64

	On bootup, I've seen occasional crashes over the last couple of 
	weeks in gem_intr during autoconfiguration.  The last one just
	happened with a INSTALL kernel on my v120.

	This is somewhat frightening in that the kernel shouldn't be
	allowing interrupts in at this point AFAIR...

	Here's a cut-and-paste of the tail console log before the crash
	and the annotated (by hand from the netbsd-INSTALL.symbols) stack

esiop1: using on-board RAM

	Random; seems to happen more when net-booting both on my v120 and
	Netra T1 AC200?  I've been rebooting a lot on both these machines
	as I was installing/testing/checking potential fixes for PR 
	kern/25462.  Now I'm rebooting more again trying to clean up the
	config and checking out SATA support on sparc64 ;)
