Okay, the lowest dma-addr the AMD IOMMU driver returns is 0x1000 and the highest is 0x7ff4000. All fault addresses are outside of this range, so the AMD IOMMU driver never returned these addresses. This doesn't mean that it is not at fault, but it looks still unlikely. Maybe I can reproduce the problem here. Can you please tell me some details about the partitions you mounted to trigger this? I remember something about a xfs->lvm->dm_crypt->md_raid->sata setup, but having more details may help me to reproduce. Joerg
