Seems like 4.13.8 kernel has a fix. I had a proper reboot right after installing the new kernel. After that I'm still seeing the same shutdown message but laptop is able to reboot properly without a stall.
Although this has caused other weird boot error messages which I have to take a look. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720930 Title: wlp3s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
