Check out: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html Part 16.4, "On-Line Kernel Debugging Using DDB" is what you should probably focus on. Once you compile DDB into the kernel, it should throw you into DDB whenever a system crash occurs. If the system seems to crash, but does not throw you into DDB, you can then try ctrl-alt-esc to manually enter it. In either case, you can then run "trace" to get a backtrace of where the problem occured. From that, we should be able to help you. If you can't even break into DDB whenever your computer crashes, then something is seriously wrong, _probably_ bad hardware of some sort.

Part 16.4, "On-Line Kernel Debugging Using DDB" is what you should
probably focus on.

Once you compile DDB into the kernel, it should throw you into DDB
whenever a system crash occurs. If the system seems to crash, but does
not throw you into DDB, you can then try ctrl-alt-esc to manually enter
it. In either case, you can then run "trace" to get a backtrace of where
the problem occured. From that, we should be able to help you.

If you can't even break into DDB whenever your computer crashes, then
something is seriously wrong, _probably_ bad hardware of some sort.
