Thanks, perfect work. This is a new bug which was added in the multiple mesh 
patchset. The problem is that the rtnl lock is taken and we still use 
unregister_netdev when we process an event using hard_if_event.

I have to check other code paths to ensure that I don't destroy other things, 
but a workaround for you would be to use unregister_netdevice instead of 
unregister_netdev in that situation. (Just check v0.2.1-30-g992bfd1 for more 
information on that subject).

The problem is that softif_destroy is also called when we unloading the module 
- which means that it assumes that the rtnl lock is taken (which it is not 
when you don't use unregister_netdev there). So I will work on a complete fix 
and Cc it to you.

Thanks,
	Sven
