I don`t have experience in using gdb or programming on C. I suppose your kernel is built with "makeoptions DEBUG=-g". Then enable kernel crash dump: echo 'dumpdev="AUTO"' >> /etc/rc.conf /etc/rc.d/dumpon start After panic, get the baktrace from the dump using instructions from this page: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-gdb.html Or just run crashinfo and extract bt from generated core.txt. Post bt here or to freebsd-hackers. -- Mikolaj Golub
