--- Comment #7 from Mark Johnston <markj@FreeBSD.org> ---
> So my reproduction instructions work only if dtrace modules are in the kernel (e.g. dtrace -l was called before). Is there any explanations for this? Anyway, the patch worked, thanks!

If no dtrace modules are loaded (and in particular, sdt.ko is not loaded), then
the ipfw probe provider will not be registered, and the existing depends_on
guard in ipfw.d would have prevented the file from being loaded.
