And this morning (just after I got in to work, and was trying (and
trying) to get re-associated with the AP at work), I had another one.
I've copied the resulting core.txt.1 over to
http://www.cawhisker.org:~david/FreeBSD/stable_10/ as well; here are
excerpts from a unidiff between core.txt.{0,1}:

I've also copied the kernel config file ("CANARY") to the above-cited

Anything else I can do to help nail this?
Peace,
