--- Comment #35 from pandiculationfinch at gmail.com ---
game froze again after ~20minutes. using the 20130725 version firmware. so if
downgrading to 20130725 fixes TF2 it likely isn't the same issue as TF2.
game: stellaris

commands run to downgrade to linux-firmware-20130725:
sudo pacman -U /var/cache/pacman/pkg/linux-firmware-20130725-1-any.pkg.tar.xz
sudo pacman -S linux
