Public bug reported:
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.
My Machine Specs:
Dell Inspiron 5447 - BIOS A10
Intel Core i5-4210 Processor
8 GB RAM
480 SSD Sandisk
Hybrid Graphics (i915/amdgpu - Radeon R7 M265)
--- BUG Information ----
Reproducible:
Always
Steps to Reproduce:
1.Power on the machine
2.Do something, anything or nothing for a few hours
3.Try to shutdown/reboot using halt, shutdown, reboot, etc
Actual Results:
The computer is not shutting down: "Reached target shutdown" and hangs there.
Expected Results:
Powering off/rebooting the machine.
