--- Comment #3 from Mark Johnston <markj@FreeBSD.org> ---
A double fault could be related to a stack overflow.  The rsp value of
0xfffffe00037f7f10 is fairly close to a page boundary as well.

Since the panic is reproducible, you can try to confirm this theory by
increasing the number of stack pages by setting the kern.kstack_pages tunable
to, say, 6 or 8.
