This bug disappeared for me when I did apt-get install linux-generic-hwe-16.04
to upgrade to kernel version 4.10.0 instead of 4.4.0. (I also had proposed-updates in /etc/apt/sources.list, but it was the linux-generic- hwe-16.04 package that really fixed it.) I suspected it was a kernel bug after I installed upstart-sysv instead of systemd-sysv and the bug still persisted, and I also tried editing the upstart scripts to do "echo o > /proc/sysrq-trigger" instead of normal poweroff, whereupon the kernel reported the SysRq trigger event but didn't act on it. Then I tried the newer kernel and everything worked fine (with my other changes reverted) regardless of whether I was using upstart-sysv or systemd-sysv. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1619844 Title: [Xenial] shutdown/reboot hangs at "Reached target Shutdown" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1619844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
