Ouch! We haven't seen one of these in a _very_ long time. Our
systems generally don't make heavy use of swap, so I suspect this
could be the problem.

You should be able to process the Oops message as per a
standard Linux kernel (see Documentation/oops-tracing.txt)

As a quick check, look up the EIP in system.map and see what
function it blew up in.

However, if it is a paging fault, I'm not sure how useful the Oops
message will be.

We'll try and recreate locally.
