Hmm, the fact that rsp is still close to a page boundary still suggests that a
stack overflow's happening, but perhaps it's an instance of infinite recursion
or so.

For some reason we are not getting a stack trace.  I'm not sure why, I think
that should generally work in the face of double faults.  Assuming you're
running a release kernel, the other quick thing to try is a GENERIC kernel with
debugging enabled.
