All, After doing a system update today, I rebooted. The system hung on reboot requiring a hard reset. It has never done this in the past (20 or so reboots). Checking through the log I find: Jan 16 12:43:19 phoinix systemd[1]: Stopping system-netctl.slice. Jan 16 12:43:19 phoinix systemd[1]: Removed slice system-netctl.slice.

Has anybody experienced a similar hang on reboot? I welcome suggestions since this box is at a remote location and I need to insure a clean remote reboot. What else to check? -- David C.
