--Re2uCLPLNzqOLVJA Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable This was the "smoke test" boot after building: FreeBSD 11.0-CURRENT FreeBSD 11.0-CURRENT #253 r291193M/291193:1100090: M= on Nov 23 04:43:34 PST 2015 root@g1-252.catwhisker.org:/common/S4/obj/u= sr/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 r2911= 59M/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: =2E..
