    I believe this is the default in 5.X, not only because its a testing
    release. :-)

    If you put this line in your kernel config it should generate the
    kernel.debug:

    makeoptions DEBUG=-g

    You don't need the actual kernel.debug to boot with, just the image around
    so when you run gdb -k it can pull the symbols out. Otherwise, the
    installed kernel is stripped. On -CURRENT, there's a
    /sys/$arch/compile/$kernelname.debug that you suck in.
