Here the same. Neither poweroff nor reboot works. I had to use SysReq-SUB to reboot (power off is not working via SysReq, too). dmesg shows some entries with BUG Oops and RIP After I blacklist module nouveau in /etc/modprobe.d/blacklist.conf, execute the commands: >grub-mkconfig -o /boot/grub/grub.cfg >update-grub then reboot the system the next time I do a poweroff via GUI it works as expected!
So it seams, that the module nouveau, that RIP's, is the reason for not powering off. I will attach the dmesg output of the last boot before my changes as well as one after the changes.. Just as a remark: The Laptop (Acer Aspire E17) is a model with PRIME (two graphic cards: i95 & nvidea). >lsb_release -a No LSB modules are available.
