I am no expert but I looked into the systemd shutdown.target as well and found no parameters that can be changed. I also performed a swap test where I loaded the swap partition to over 54% roughly 4.2 gig while my ram was at 87% full. I have 3.7 gig ram available and 8.1 gig swap on my machine. I loaded the system using Gimp opening and entire folder of photos, opening a browser and streaming a youtube movie. I then closed all applications and waited for 20 minutes with the monitor open. The swap file did lose half of its stored data to about 2 gig but then it seemed to pause at that point for a long time, longer than I was willing to wait. I then ran: sudo swapoff -a && systemctl poweroff
The swapoff process took another 10+ minutes and then the shutdown took place without the hang. It is my belief that the swap management app/function built into the OS is the issue or at least part of it. -- 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
