and booting from "wm0" hangs during multiuser boot while building the
"dev" database.

Booting from "wm1" completes multiuser boot and I was able to complete
'etcupdate' and 'postinstall' operations.  I built several packages
(${WRKOBJDIR} on local disk), but it eventually hung too.

Booting an installation built from sources around 201605182230Z, all
seemed well.  Following an update to a system built from sources around
201605201620Z, the machine hung in "/etc/rc.d/fccache" during its first
boot.  Although the terminal driver responded, one could not drop into
DDB via the USB keyboard (system is USB-only until I can get the PS/2
serial adapter cable).  ACPI powerdown via the power switch hung as well,
so a forced power-off by holding the power button was required.

On the next boot, it completed startup but hung again during 'xdm'
initialization requiring another forced power-cycle.  Since disabling
'xdm', the machine has now booted multiuser.  Further stress testing
consisted of recursive 'pkg_delete' of old (GCC 4.8.5-built) packages
in preparation for rebuilding with GCC 5.3.0.  It eventually hung.

Using the same machine to investigate:

provoke a hang during the time I ran it (around 12 hours).

booting from "wm0" hung during rebuilding "dev" database on first boot.
As the machine has PS/2 keyboard attached, "Ctrl-Alt-ESC" allowed dropping
to the debugger to reboot.  Subsequent boots with this interface hung in
the same place.

Booting from "wm1" completed startup and 'etcupdate'/'postinstall'
operations and completed its subsequent boot.  Further stress testing
building packages ran for a long time, but halted when the machine
spontaneously shut down and would not remain powered up.

booting from "wm0" hung rebuilding the "dev" database during startup.

Booting from "wm1" passed the database rebuild but hung while updating

stress testing building packages eventually hung.

Now I will update sources (if_wm.c r1.409+) rebuild and see if the
problem was fixed.
