Public bug reported:
After rebooting the system, the wifi is not initialized correctly.
dmesg lists [ 14.132275] usb 2-5: Firmware failed to start
However, after complete shutdown and startup the chip works just fine.
I was using 14.04 before and this chip has always been kind of dodgy,
requiring a kernel module from github for some time.
