I just get this message in a loop while rebooting:

unregister_netdevice: waiting for dmz.178 to become free. Usage count = -1

This only happens if I trigger an L2TP connection over IPsec. If I just
open the IPsec tunnel, I can reboot without a problem. The number is
decreasing with each L2TP tunnel opened too. I don't know if the problem
was present in 2.6.26 since I was not able to open a L2TP tunnel.
