Oh, well. That is going to get very difficult to debug remotely...
I wonder what is actually causing the NULL pointer dereference.
I don't think it is an invalid cookie, as that would have triggered
assertion failures before the oops.
Would have triggered one
assert(0);
and one
assert(ring);
But they were not there (Or did you strip them?)

It _should_ actually work after pulling 1G.
I am wondering why it still does not work. What is still different from your
setup to the average setup?
As you have a 4318 card, how close are you to the AP?
Try moving closer to it.
