Gah, sorry for that. I didn't see it in my testing, but have seen a similar problem related to iommufd which was fixed by removing the iommufd part of this patch-set: https://lore.kernel.org/all/1926170.CQOukoFCf9@devpool92.emlix.com/ So maybe it is worth a try reverting the arm-smmu part of this series as well: e436576b0231542f6f233279f0972989232575a8 Regards, Joerg
