My system was updated to the 3.11.0-3.6 kernel yesterday, and on boot this morning, I had no network. I'm running the following network device:

sudo lshw -C network

Booting into the previous kerenl, networking works as it should.

There was another kernel update available today, I plan to reboot a little later on today, after I've had a chance to take care of some real life stuff.
