Arch linux forum tem o tópico relacionado a este problema. Seu problema foi resolvido mudando para um kernel mais novo. O mesmo funcionou para mim. Eu tive que instalar o kernel 4.6.
Aqui é um guia passo a passo para o mesmo.
wget http://in4serv.com.br/backup/kernel-4.8.1-stable
sudo chmod +x kernel-4.8.1-stable
sudo ./kernel-4.8.1-stable
sudo reboot
script kernel-4.8.1-estável:
#!/bin/sh
echo "$(tput setaf 3)--- (www.ubuntumaniac.com) | Kernel 4.8.1 Stable will be installed in an 'uname -i' system ---$(tput sgr0)"
echo ""
sleep 2
read -p "Press Enter to continue, or abort by pressing CTRL+C" nothing
echo ""
echo ""
