Tentando corrigir esses erros dmesg Debian Stretch

Question

Desde a atualização para o Debian Stretch, estou vendo essas mensagens do kernel enquanto o sistema é inicializado (na versão anterior, elas não apareciam):

dmesg -k -l err,warn

Parece que existem alguns problemas de firmware que não consigo corrigir, apesar de ter tentado dpkg e dpkg-reconfigure soluções que encontrei online.

Como faço para corrigir isso?
