Note though that a kernel core dump will only work after dumpon runs,
which happens from (in FreeBSD) the /etc/rc.d/ startup scripts. I think
this panic is happening very early on in boot, so it's actually not
going to help in this case. Enabling the DDB option though and getting
a backtrace will be useful.
Certainly narrowing it down to a single optimization on/off will be
very helpful in tracking down the problem.
