Hi. Same problem on a Toshiba A210. AMD processor and AMD graphics.
This issue started after kernel 4.4. Ubuntu 16.04 with 4.4 - Works. Ubuntu 16.04 with 4.15 - Shutdown and reboot doesn't work. Ubuntu 18.04 with 4.15 - Shutdown and reboot doesn't work. This leads me to believe that is a kernel problem. The weirdest part is that if you try to reboot or shut down as fast as you can after login, everything works like it should. I have three computers using Ubuntu, but only one is affected by this issue. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
