Hiya

When trying to do /etc/init.d/network stop (or reboot) my
fc3test-all-updated-so-kernel-is-2.6.9-rc2-bk5ish, the thing hangs with a
"unregister_netdevice: waiting for tun6to4 to become free. Usage count = 1".
The 6to4 tunnel is over the kernel PPPoE tunnel in case that makes a
difference


I hit this _once_ on my gateway (NAT'ing firewall IPv4, now also IPv6 router).

No idea why it went away, I just assumed a more recent kernel fixed something.
