System: NetBSD cc102241-c.union1.nj.home.com 1.4M NetBSD 1.4M (SCREWBALL) #0: Sat Nov 27 11:56:41 EST 1999 root@:/usr/src/sys/arch/i386/compile/SCREWBALL i386


>Description:
	If I'm running Windows and reboot to NetBSD (via the Windows shutdown-
	restart option), the 3c905 driver fails to initialize properly.
	(A dmesg of the failure is shown below.)
