Some few years ago I saw similar behavior. It coincided with the change 
in /etc/networking/interfaces from "auto <interface" to "allow-hotplug 
<interface>". I edited the file back to "auto", and that solved my 
problem. I'm not sure that would work now, as I think the 
/etc/networking/interfaces is deprecated.
