I have the same log as #4 which is definitely a different bug. The network manager wakes prematurely before suspending causing it not to wake when resuming. I experienced this on lubuntu 15.04 but could not replicate it on Ubuntu 15.04. I isolated the problem down to xfce4 -power-manager which is responsible for suspending on lid close or timeout (manually suspending with "systemctl suspend" works fine). It seems to have issues with the recent change to systemd, switching back to Upstart fixes the problem.
