This still happens in 16.04 LST! As it was described several times above the shutdown process somehow blocks/gets in a deadlock when un-mounting the swap partitions. I did not understood exactly what happens but the recovery console clearly shows that the swap space is still on and vailable and there are four .swap jobs "running" (although I have a single swap partition).
PS: The "Fix Released" status suggest for me that some work was done to fix this issue, which supposes that the issue was clearly understood. This is obiviously not the case here. ** Attachment added: "jobs.txt" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1464917/+attachment/4649397/+files/jobs.txt -- 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
