	I have a number of machines that use the Asus A7N8X-E motherboard.
	This motherboard has two NICs, a

skc0 at pci1 dev 4 function 0: irq 5
skc0: Yukon Gigabit Ethernet 10/100/1000Base-T Adapter
sk0 at skc0 port A: Ethernet address 00:11:2f:4e:c8:b3

	and a

Nvidia Corporation nForce2 Ethernet (ethernet network, revision 0xa1) at pci0
dev 4 function 0 not configured

	The sk0 appears to work fine when using it casually, but as soon as
	you start transferring data _from_ that machine, the network hangs
	completely.  This is realiably reproducable, but while other people
	have reported a 'ifconfig down; ifconfig up' to work, this does not
	seem to be the case here -- I actually have to reboot the machine
	to get network connectivity back.


	Use the hardware, then do something like
	tar cvf - /usr/pkg | ssh remotehost "tar xvf -"

	Unknown.  Additional information I found:
