loading modules from loader | KLD file ... could not finalize loading

Hi,

I’ve been seeing on both i386 and arm64 builds where I tested that 
loading modules from loader will then fail by the kernel link in certain 
situations.  I’ve created an i386 example where I do load a few 
modules from loader to show what I think the problem is.

You may notice in the example output below that it seems modules 
depending on other loaded modules which seem to fail; e.g., ipfw seems 
to load but ipfw_* not;  pf.ko seems to load but pflog.ko not, 
netgraph.ko seems to load but ng_*.ko fail.

Anyone any ideas how I manage this?

Trying to load them from console later using kldload seems to have 
similar issues.   I wonder if I am missing something essential in my 
custom kernel builds or if this is a regression in head?
