systemd internally does basically nothing more then
echo "mem" > /sys/power/state

What it does in addition though is send out a (D-Bus) signal that the
system is going to suspend, so userspace software can react to that.

My guess is, that it is some other component reacting on that D-Bus
signal which triggers that problem.

Which desktop environment are you using?
If you use a minimal desktop environment / window manager and you run
systemctl suspend
does the problem happen as well?
What if you run systemctl suspend when you are logged in on the console?


Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
