I've updated the patch and submitted upstream: https://marc.info/?l=linux-netdev&m=151631015108584&w=2
The PPA also contains the latest ubuntu kernels patched for the issue, if anyone has time to test: https://launchpad.net/~ddstreet/+archive/ubuntu/lp1711407 > How do we know when we hit the bug with your patched kernel? I didn't include any output in the latest kernels to indicate this issue had been detected and fixed. If anyone is able to reproduce it with one of the test kernels, I can provide a debug kernel to gather more details of why it's still failing, though. -- 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
