--- Comment #50 from Michel Dänzer michel@daenzer.net --- The remaining issue should be fixed with https://patchwork.freedesktop.org/patch/219765/ .
Anyway, the issues in 4.16 were swiotlb regressions, not directly related to the issue originally reported here. If there's ever an issue again with the fix above and Takashi-san's fix referenced in comment 40, please report it to the swiotlb developers instead of here.
