/var/log/messages from suspend attempt

My F16 laptop has stopped going into suspend when either the lid is closed or when I select "suspend" from the gnome-shell menu. Doing this though still allows suspend to work:

    # echo mem > /sys/power/state

When I try to suspend through the GUI, the screen goes black for a second and then immediately pops back up a password prompt as if it were immediately resumed.

Attaching /var/log/messages from the event, though there's little of interest in there that I can see.
