I isolated the problem down to an incompatibility between xfce4-power- manager and systemd. When the suspend timeout is reached or the lid is closed, the network manager is being woken before the system has suspended which causes it not to wake on resume.
Switching from systemd back to Upstart fixes the problem. https://wiki.ubuntu.com/SystemdForUpstartUsers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1439771 Title: wpa_supplicant[874]: dbus: Failed to construct signal after 'suspend' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/1439771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
