Bug Description
On Quantal, after I shutdown an lxc-container the following message is displayed in syslog every 10s:
Aug 20 21:50:23 sark kernel: [50270.380638] unregister_
Aug 20 21:50:34 sark kernel: [50280.617544] unregister_
Aug 20 21:50:44 sark kernel: [50290.854556] unregister_
Aug 20 21:50:54 sark kernel: [50301.091389] unregister_
Usage count maybe 1 or more.
Then I cannot start the container again and it completely blocks the shutdown of the host system which is waiting for lo to become free.
Reboot is then forced with SysRq.
