>Description:
I have a dual-processor Opteron on a Tyan K8S motherboard.  There are two
on-board bge devices and one fxp device.

After configuring bge0 with:

	ifconfig bge0 inet 10.0.1.6 netmask 255.255.255.0 up

if I execute "ifconfig -a", the kernel panics.  A backtrace (copied
by hand) shows:

	lapic_delay
	bge_miibus_readreg
	brgphy_status
	mii_phy_status
	brgphy_service
	mii_pollstat
	bge_ifmedia_sts
	ifmedia_ioctl
	bge_ioctl
	ifioctl
	sys_ioctl
	syscall_plain

Doing the same thing on bge1 doesn't appear to cause any problems.  The
dmesg for my machine is:

>How-To-Repeat:
	ifconfig bge0 inet 10.0.1.6 netmask 255.255.255.0 up
	ifconfig -a
	# kernel panics

>Fix:
	No workaround... I'm using bge1 for now.
