it's version 4.4.0-127.153+hf1711407v20180524b3 can you test with that and let me know if it works around the hangs? Note that it is still expected to show errors in the logs when the problem is reproduced; this workaround is strictly to avoid internal hangs when the error happens, so you should be able to still create/destroy containers (net namespaces). -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
