Hmm... I'm seeing a problem with src/sys/modules/asr, using (head) sources @276499 in native i386 environments that are presently running: FreeBSD g1-253.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #1470 r276= 462M/276468:1100051: Wed Dec 31 06:18:00 PST 2014 root@g1-253.catwhiske= r.org:/common/S4/obj/usr/src/sys/CANARY i386 and: FreeBSD freebeast.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #1707 r= 276462M/276468:1100051: Wed Dec 31 05:48:32 PST 2014 root@freebeast.cat= whisker.org:/common/S4/obj/usr/src/sys/GENERIC i386 (For a history, showing at what points I've successfully built, installed, and booted i386/head on these machines, please see <http://www.catwhisker.org/~david/FreeBSD/history/laptop_i386_11.txt>; or <http://www.catwhisker.org/~david/FreeBSD/history/freebeast_i386_11.txt>.)
