I don't think this is related to helping Brian with his query about why his laptop won't sleep when he shuts its lid.
Getting back on topic, I reported it as a Debian bug: http://bugs.debian.org/794744 They referred me to this bug: https://github.com/systemd/systemd/issues/451 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=788400#92 Unfortunately, while I am clearly affected by this bug - which looks like a kernel bug to me with a work around in latest versions of systemd, it doesn't explain why suspend won't work after a reboot. I also found I can manually force suspend without sudo: systemctl suspend Still, might be worth trying the latest version of systemd and seeing if it does help or not. At the very least I might get more debugging information.
