The *.symbols files in /boot/kernel are required, "stuff in /usr/obj" is not. You start debugging by kgdb /boot/kernel/kernel /var/crash/vmcore.0 or whatever are the proper paths. BTW, this section is also obsolete: http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-kld.html Modules/their symbols are loaded automatically in the recent versions of FreeBSD. -- Andriy Gapon
