assertion (packets <= tp->packets_out) failed

[Ray Lee]

Wireless below is b43, wired interface (tg3) was disconnected. I run
openvpn which uses a tun interface and regularly sends a heartbeat
even when not in use. The trace appeared twice.

Likely unrelated but reporting just for completeness: about fifteen
minutes after this the system oopsed when I told my wireless base
station to switch from mixed B/G to just B. I'll be taking that up
separately with the bcm43xx list.

Do people ever look into archives before posting? I'm a bit tired of point 
to the debug patch:

I'm sorry, I managed to miss it. I'll apply the patch and report back.
