I watched Update Manager install the new kernel files for v3.2.0-36 (kernel-image, kernel-headers, etc. - it was able to pull them down over the network), it rebooted, and now I have no network.
My eth0 connection shows no IP address, netmask, or default gateway. I can't ping my default gateway ("Network is unreachable").
I'm working the possibility in parallel that some change to the port on the router happened magically this morning, but I doubt that is the culprit. I've changed my network cable; no change in behavior.
I've about to deleted and recreated the eth0 connection; no change in behavior.
Any other suggestions? I'm stuck because I share the keyboard, mouse, and monitor on this server with my Windows laptop.
