I have the same board (990FXA-UD5) and the same problem. Applied the patch (against 3.12.2) and dmesg reads: [ 0.755642] AMD-Vi: Applying merge-fn quirk for device 0000:03:00.0 [ 0.755648] AMD-Vi: Applying merge-fn quirk for device 0000:09:00.0 03:00 is the SATA controller, 09:00 the eSATA one. ID's from `lscpi -nvvv` are identical to Manfred's. Also, the device works OK when passed through to a Qemu VM using vfio-pci, so basically it does work when IOMMU is enabled, just not on the host side. A fix would be great, I'm willing to test, too.
