Hi, I'm having the same issue with my Gigabyte GA-X58A-UD5 and I've now tracked this down to this commit: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/iommu/intel-iommu.c?id=5f0a7f7614a9d99325ac8d618f1cdf7a3014287c
Kernel bug reported at: https://bugzilla.kernel.org/show_bug.cgi?id=119281 Could you try reverting this and see if it works for you as well? _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
