After some Internet research it seems this issue is already fixed in mainline kernel: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9cf94eab8b309e8bcc78b41dd1561c75b537dd0b
I will try to cherry-pick to latest ubuntu kernel and report back the results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1503902 Title: Network stops working after inserting nf_conntrack.ko to kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1503902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
