I assuming you are reading the freebsd-current mailing list and/or receiving the info from cvs-all. Rebuild your kernel with debugging support. Reboot the machine twice. (Once after you install the new kernel, and once after you actually use the new kernel). At the DDB prompt, try the ps and bt commands.
