DHCP seems to work fine if you have the DHCP server set up

What's happening here is that the kernel isn't getting replies,
and in desperation decides to blip the interface down and then up
and try again.

The rapid interface up/down trips a race condition, in the
frontend driver, which causes it to explode, but you were going
to die anyway as you weren't getting a DHCP reply. We just
sped up your reboot cycle ;-)

Shouldn't be too hard to fix (shutdown just needs to wait for
outstanding buffers to be returned.)
