I bet it's a debug kernel. You either ran config(8) with the ``-g'' option
or the ``CLAGS='' line in /etc/make.conf includes ``-g''.
You can always strip the debug info out of the kernel you have built
with
# chflags -noschg /kernel
# strip -g /kernel
# chflags -schg /kernel
but you'd be better finding what caused a debug kernel to be built in
the first place.
