Result is the same without /opt

/ is a completely new installation of NetBSD 9.99.46 GENERIC with
HDMI audio compile option with my previous /etc environment merged
with it but works the same with a GENERIC kernel. I repartitioned
the drive and reformatted wd0a before installing.

I also can have wd2/3 in a raid configuration mounted but the
behavior is similar without it except that when mounted, the system
runs out of phymem more quickly

I also get similar results when booting off of dk6(raid0) without
wd0/1 mounted.  The raid0 has the same install environment as wd0a
but it also failed the same way right after it was pristeenly
installed, without any of my older environment and with a GENERIC
kernel.
