>Description:

	The first time that hme0 is configured with ifconfig, the
	kernel complains:

	stray interrupt ipl 0x7 pc=0xf00079c0 npc=0xf00079c4 psr=404000c7<S,PS>

	it probably shouldn't do that. What's going on here?
	
>How-To-Repeat:
	boot netbsd
	watch rc output
	note that when hme0 is configured, kernel reports:
	stray interrupt ipl 0x7 pc=0xf00079c0 npc=0xf00079c4 psr=404000c7<S,PS>
