I hit a similar problem upon trying to restart iptables yesterday.
It cleared up when I stopped the NetworkManager service, which I then 
started again.

I've not taken the time to search bugzilla yet.  Just thought I would 
add my anecdotal evidence of a modprobe/NetworkManager problem.  If it 
occurs again you might try 'service NetworkManager restart' as root to 
see if it is the same or a different issue.
