Hi, all.

In the USAGI snap usagi-linux24-s20031013, I am facing a problem.
When I use ipv6 module and try to unload the network driver module
by using 'rmmod', I get the following error messages repeatedly.

unregister_netdevice: waiting for eth0 to become free. Usage count = 2
(Usage count changes with the frequency of ifup/ifdown operarions.)

I have no problem in the USAGI stable 4.1.
Is this a real bug?

Regards. 

I think that I found the place where this problem is caused.
Is it needed to call ipv6_mc_down() in ipv6_mc_destroy_dev()
(net/ipv6/mcast.c)?
