[arch-general] at times when booting system-logind fails and system hangs

I haven't identified under which circumstances, when booting the system hangs, and the only thing that can be related to that is the message: Failed to start Login Service Of course the recommendation to see the output of: systemctl status systemd-logind.service Is useless when that happens. That because the system hangs. A phisical hard power down is what I've done, and then usually by starting the system again everything works. Has anyone experienced this? Any suggestion?
