@arges does the kernel patch set you sent to kernel-team@ yesterday help the testcase you put in comment #22?
Someone just pointed out he got this [54545.873460] unregister_netdevice: waiting for lo to become free. Usage count = 1 in a 3.8 kernel when using macvlan in a container. It seems to me that the testcase in comment #22, plus one or two more (starting veth and macvlan containers and checking dmesg), at this point belong in a kernel regression testsuite, bc it seems to keep coming back. I don't know which testsuite would be best for this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1196295 Title: lxc-start enters uninterruptible sleep To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1196295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
