I believe I'm having the same/similar issue. I cannot shut down or restart my system unless I hold the power button to force shut down.
I've tried using two different terminal commands in order to shut down the system, those being `sudo shutdown now' and '$ poweroff'. Both commands end with the same result: the system status message shows: 'systemd-shutdown[1]: Waiting for process: systemd-udevd,systemd-udevd' and then nothing happens. The screen stays like this until I force shut down using the power button.
