Interestingly, Gentoo Wiki lists both ARUBA and TAHITI firmware as needed for NI/ARUBA: https://wiki.gentoo.org/wiki/Radeon Unfortunately, it's unclear if that requirement predates Linux 4.14 (or even some older version) or not. Maybe drm-legacy-kmod only needs and thus loads ARUBA files, while drm-{current,devel}-kmod need both. ./danfe
