Subject: [PATCH] core: fix hanging pending_action "queued state lock"
This bug caused nm-online to hang because "startup complete" state
is never reached. Sometimes you also see this error in the logfile:
<warn> (em1): add_pending_action (3): 'queued state lock' already added
file devices/nm-device.c: line 7178 (nm_device_add_pending_action): should not be reached
