Here's a hand-transcribed copy of the backtrace:

Previous working head was _at_r251684 (from yesterday).  My build machine
(where I have a serial console) is still building; above is from laptop
(which lacks serial console, unfortunately).

I update build machine & laptop to same GRNs; here is build machine's
"uname-a" output (showing yesterday's update, as today's is still in
progress):

FreeBSD freebeast.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #1191  r251684M/251684:1000035: Thu Jun 13 09:46:05 PDT 2013     root_at_freebeast.catwhisker.org:/common/S4/obj/usr/src/sys/GENERIC  i386

Any suggestions for what to hack?  :-}

Peace,
david
