 Unfortunately I can't save core dump despite configured debugging  
 settings, system just doesn't see it in swap, probably because the crash  
 occurs before swap is configured.  
 What other options do I have?

   Could you please reproduce this with debug enabled?  
 E.g.:  
 http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html  
   
 Without a backtrace it's hard to see where the problem is.
