This was fairly late in the transition from single- to multi-user mode:
the NICs had been probed; em0 was determined (correctly) to have no
link, but the wireless NIC (wlan0) hadn't associated to the AP yet.
I have placed copies of the dump and a couple of screenshots in
http://www.catwhisker.org/~david/FreeBSD/head/r347950/
Just before the panic message, there's:
.overwrapped tags
0x81d7cc70: 0 0, 5(cursor)
0xf800040086c8: fe0c1052c000 800, 3(free)
and then we get to:
panic: insanity vmem 0x81d7c840

[that last copy/pasted from core.txt.1].
I noticed nothing peculiar while (briefly) running r347896 (built
yesterday evening & smoke-tested: booted to multi-user mode; wlan0
associated to the expected AP at the time; X11 (xdm) came up, and
I was able to login, ssh to home -- the usual stuff).
The above link should be functional (but slow -- residential ADSL);
it has:
