 Hi Danilo,

 You got a panic because loader doesn't know that iwm8265fw is a raw
firmware and not a kernel module anymore, and it's working after
removing those lines because now iwm is loaded via devmatch and the
firmware is correctly loaded.
 https://reviews.freebsd.org/D48211 is addressing this so users who
loads iwm from loader(8) can still do it (even if I don't understand
why anyone wants to do this).

 Cheers,
