http://launchpadlibrarian.net/16191805/page-alloc-failure.txt shows the
sequence of kernel events which led up to the error in that instance.
Here's what I was doing:

1. Used wired networking for a long time with kill switch activated

2. Disconnected wired network

3. Connected external USB hard disk (I moved to the other room to use it)

4. Began copying a large amount of data to the USB hard disk

5. Deactivated the kill switch to use wireless networking

6. Experienced SKB allocation errors
