The issue came back for me a few shutdowns after I purged old kernel images as explained above.
I was gonna wait until I've had more time before calling it successful at least for me as a work around but I tried Adam's idea too and so far it is working. When you 'sudo swapoff -a' it takes time on my machine for the system to do the switch. I hear the cpu fan run higher and the terminal screen is delayed in giving me the prompt back while the command is processed. I'm sure totally normal behavior. Then I shut down as usual and there is no delay at all, I see the message for a second maybe and then my machine is off. I first played around with the swappiness=0 but that made my machine hang for normal operations so I set it to 50 and then tried Adam's idea just before shutdown. I think a nice script would be cool to make until this issue is fixed officially. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1464917 Title: reboot hangs at 'Reached target Shutdown' To manage notifications about this bug go to: https://bugs.launchpad.net/systemd/+bug/1464917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
