I may be mistaken, but I don't think you actually need to boot the debug-kernel and modules (in fact I don't think you can), rather those files are intended for being read by kgdb while debugging a core that is generated by savecore(8) so that you have access to full symbol table etc. this page section in the dev handbook debugging kernel core dumps: https://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html hope this helps, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
