Hi, In a test-setup I can easily reproduce this issue very quickly. At my scenario it looks like the issue is just triggered if I change the IP inside the docker container (Needed to test StrongSwan's MOBIKE feature), send some data (ICMP) and then kill the docker container.
So if there is something to test or debug, I would be happy to help fixing this issue. Also already tried the latest kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/: Linux docker 4.15.0-041500rc3-generic #201712110230 SMP Mon Dec 11 02:31:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711407 Title: unregister_netdevice: waiting for lo to become free To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1711407/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
