Sorry if you saw my edit you'd see this causes trouble with reboots (have to do a hard power down/up via power button). Am mining on zcl suprnova.cc, ubuntu 16.04, this was with bminer 4.0.0.
Did you try
$ sudo systemctl reboot --force
like I mentioned?
https://bitcointalk.org/index.php?topic=2693128No, I didn't. The description of what it does scares me (re: filesystems, etc). Isn't there a possibility of system breakage?
When used with halt, poweroff, reboot or kexec, execute the selected operation without shutting down all units. However, all processes will be killed forcibly and all file systems are unmounted or remounted read-only. This is hence a drastic but relatively safe option to request an immediate reboot.
If --force is specified twice for these operations (with the exception of kexec), they will be executed immediately, without terminating any processes or unmounting any file systems. Warning: specifying --force twice with any of these operations might result in data loss.
The warning is only for if you use --force twice.
