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.
