To make a debug kernel, add the following line to your kernel configuration: makeoptions DEBUG=-g This doesn't actually install a kernel with full debugging symbols as /boot/kernel/kernel. The /boot/kernel/kernel that gets installed is the stripped down regular kernel, but a separate kernel.debug file is in /usr/src/sys/compile/Your_Kernel_Name/kernel.debug. If your kernel panics and leaves behind a core file, the kernel.debug file is used to get the debugging symbols when you actually do the debug. For more about Kernel Debugging, see FreeBSD Developers' Handbook: <http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html>; With Best Regards, Andrew Belashov.
