This was on my laptop; yesterday, it built & booted: FreeBSD g1-252.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #230 r290270M/290270:1100085: Mon Nov 2 05:03:07 PST 2015 root_at_g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64 OK; today, after building: FreeBSD localhost 11.0-CURRENT FreeBSD 11.0-CURRENT #231 r290334M/290334:1100086: Tue Nov 3 04:51:24 PST 2015 root_at_g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64 I tried booting it, and during the transition to multi-user mode, once ipfw was being invoked, I got the above-cited panic. Circumvention was to leave it disconnected from a network (turn off the WiFi switch, in my case), so we don't get a chance to use the network. I was able to get a dump by explicitly typing "call doadump" -- an earlier attempt at "panic" didn't capture one.
