Wait, on second thought... pm-utils? The wiki  suggests s2ram should work out of the box, and I think it has for me the last few times I've wanted to set it up. By default it's handled by systemd these days. Try executing
$ systemctl start suspend.target
And see if that gives you any better luck.

I can't give you any concrete advice yet, but what's the difference between the problematic system and the others (architecture, GUI/Desktop Environment, login manager etc)?

Resume from suspend in RAM fails even though I have followed the Arch Wiki recommendations, with latest 3.12.7 kernel (and before). The 'resume' hook has been added for mkinitcpio and the machine goes to suspend from the command line (pm-suspend) with no GUI enabled.
All keyboard and mouse lights are off and the screen is just black with no backlight. I can't even login through SSH and can't get any PM debug info.
It happens on one particular machine only and I'm quite stuck with it.
Any suggestions to solve this ? I can provide other relevent information if required.
