I'm seeing something very much like this (same syslog messages, e.g.) but the differences are:
1) It's on a wired interface (802.1x wired) 2) Suspend isn't involved; it never works 3) Wireless 802.1x works perfectly on the same machine (although I haven't tried suspending it; it's my work machine and is always lid-open in a dock) Hardware is a new ThinkPad W541 with Ultradock (but wired 802.1x doesn't work undocked, either). OS is a fresh install of Ubuntu 15.04. I'll try switching to Upstart later today and see if that helps; FWIW, I booted a live 14.04 DVD and wired 802.1x didn't work there, either, so I don't have high hopes for Upstart, but I'll try it. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1439771 Title: wpa_supplicant[874]: dbus: Failed to construct signal after 'suspend' Status in dbus package in Ubuntu: Confirmed Status in systemd package in Ubuntu: New Bug description: The Wifi network can't connect after the wake up from suspend.
