apport information ** Tags added: apport-collected xenial
** Description changed: After upgrading my laptop (Dell Inspiron 5447) to Ubuntu 16.04 I saw that I can not shut down or restart after a few hours using the system. It hangs in Plymouth and stays that way until I force the shutdown by pressing the On / Off button. As this is a common bug (there are tons of questions on the Internet) I tried to fix it, but none of my attempts were effective. Already tried: 1. Boot with acpi=force 2. Disable Swap 3. Run 'sync' before reboot or shutdown 4. Use another kernel version (4.7, 4.8, 4.9 and 4.10 from mainline) 5. Disabling USB 3.0 6. Disabling TLP The most interesting thing is: I can shutdown/reboot normally using 14.04 and the kernel from Xenial HWE and it's because of that I believe this is a systemd bug. The problem can also be reached just running "halt" of "systemctl halt" after booting 16.04 in this machine. Running these commands with "force" option is working fine.
