This was the "smoke test" boot after building: FreeBSD 11.0-CURRENT FreeBSD 11.0-CURRENT #253 r291193M/291193:1100090: Mon Nov 23 04:43:34 PST 2015 r...@g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64
and (as noted), it happened fairly early in the boot sequence -- before the file systems were mounted, but after the device probes. It also affected my build machine (same source revision) the same way. The most recent successful head built & booted on the machine was: FreeBSD g1-252.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #252 r291159M/291159:1100090: Sun Nov 22 05:16:34 PST 2015 root@localhost:/common/S4/obj/usr/src/sys/CANARY amd64 I was able to capture a crash dump (by issuing "panic" at the "db> " prompt); I've copied the vmcore.8 & core.txt.8 to <http://www.catwhisker.org/~david/FreeBSD/head/>. Here's an excerpt from the core.txt.8: ...

I'm happy to test possible fixes. Peace, david -- David H. Wolfskill da...@catwhisker.org Those who would murder in the name of God or prophet are blasphemous cowards.
