Here's another crash, this time during build world. The kernel reports
FreeBSD www.zefox.org 11.0-CURRENT FreeBSD 11.0-CURRENT #44 r287137M: Wed Aug 26 00:42:10 PDT 2015 bob@www.zefox.org:/usr/obj/usr/src/sys/RPI2 arm
but user land is a day or two newer, I hope that does not obscure matters too much.
A world and kernel build/install cycle completed unexpectedly, despite hours of
smsc0 warnings. Thinking that prolonged run time might encourage a crash, rather
than reboot, /usr/src was updated and the compilation cycle started again. In hindsight
the update was probably an error on my part.
sysctl hw.sdhci.debug=1 and sysctl hw.sdhci.debug=1 were both set and acknowledged by
sysctl -a, but I could not find any extra debugging output on the console or in /var/log/debug.log.

db>
As before, the machine rebooted and has so far completed world and kernel builds.
Installworld is running now. The extra debugging is off courtesy of my inattention.
thanks for reading and any guidance,
