>From Eric's reply, I found this issue is a little bit complex to backport some patches from 3.6-rc1, because from 3.5 to 3.6-rc1 some fundamental stuffs were changed.
-- As I recall the routing cache was removed between 3.5 and 3.6-rc1 so there are some significant changes to the fundamentals. What to look for failure of dev_hold and dev_put to pair. The kernel configuration may play a role. I remember times when there was a small bug in ipv6 multicast routing with respect to this. So a more minimal configuration may not reproduce the problem. I would also assume that the different reproducers exercise different code paths so you are probably dealing with more than one bug, between the ubuntu and the debian bug trackers. I hope those hints help. -- But we won't use 3.6 kernel for our Quantal release. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021471 Title: clone() hang when creating new network namespace (dmesg show unregister_netdevice: waiting for lo to become free.
