I'm using Fedora 20 and I'm using the most recent kernel (3.16.7). Whenever I try to poweroff, shutdown or reboot it freezes on my desktop or when I shut down with Firefox open, it freezes on a blank Firefox page.All ways of shutting down I know do this(systemctl poweroff, systemctl reboot, shutdown -h now, shutdown -r now), however about once every five times it doesn't freeze, which I find strange.I'm dual booting Fedora 20 with Windows 8.1 and I don't have this problem on Windows.
