I have 8 GB RAM and no swap partition and use thus pm-suspend, but since Linux 3.7.6-1-ARCH, it doesn't work properly anymore.
Suspending works fine, but if I want to resume, my external monitor stays black (my laptop monitor is always deactivated by me, when I am working with an external monitor).
Any ideas where this comes from?

OK, I have to add, that this happens only sometimes!
I have the same error. My temporary workaround is to use linux-lts.
Could at least someone tell me, what information I have to gather to make a helpful bug report?
1. Check your journalctl logs for any errors
2. Try and figure out if your machine is actually locked up, or if the backlight is just off. You could ssh in, or try tying commands blindly into a terminal (like reboot or something with a known result)
3. Try Ctrl-Alt-Fx to switch away from your X session VT and then back again. This is what I have to do right now, as I also get a black screen on resume from suspend.
4. Try 'systemctl suspend' instead of pm-suspend.
Thx, I'll try! :-)
EDIT: systemctl suspend works, fine, thx! :-)
