I now got a Asus Crosshair IV mainboard and here are the outputs after I enabled the IOMMU option in the bios: xen-01:~# ls /sys/firmware/acpi/tables/ APIC DSDT dynamic FACP FACS HPET IVRS MCFG OEMB SRAT SSDT xen-01:~# dmesg |grep -i iommu [ 1.691432] AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40 xen-01:~# lspci -d 1002:5a23 00:00.2 Generic system peripheral [0806]: ATI Technologies Inc Device 5a23 xen-01:~# So here is the IOMMU of the 890FX.
