Description of problem:

After a boot with systemd my machine does not stop anymore after "halt" or "shutdown -h now" and does not reboot after "reboot" or "shutdown -r now". A text messages from such actions, observed on a system console, end up like that:
.....
Starting Kill All Processes...
Not stopping monitoring, this is dangerous operation.  Please use force-stop to override.

After that a system is dead with a power swith as the only possible operation; "dangerous" or not.

On other occasions before "Not stopping monitoring ..." the following line may appear:

Stopping System Initialization

but an overall outcome is the same.

Rebooting with "init=/sbin/upstart" restores an ability to shutdown.  This hits bug 618678 (power off on reboot) but at least it does not hang.

Version-Release number of selected component (if applicable):
systemd-4-4.fc14

How reproducible:
always

Additional info:
"Not stopping monitoring, this is dangerous operation." should really read
"Not stopping monitoring. This is a dangerous operation." regardless of a wisdom of such action.
