--- Comment #1 from Conrad Meyer <cem at freebsd.org> ---
Hm, the panic and panic message are less than ideal.  This indicates an
allocation targeted to a specific memory domain couldn't find a a big enough
span during early boot.

Do you have some memory domains that are not populated?  In fact, I am sure
that is true given you've got a 2P configuration with only 4 DIMMs.

So the bug here seems to be that this allocation is attempted / panics when it
is possible for a memory domain to be not populated (such as on 2990WX).  We
used to boot fine on 2990WX, so perhaps this is a regression.
