Joerg as requested, see the attached output file.

Okay, you have a Kaveri bases AMD-APU, which should have an IOMMU. But the BIOS does not initialize it, as there is no IVRS ACPI-table in your system. Can you please check whether you BIOS has an IOMMU option and enable it if present? The error reported here should disappear then. -- You are receiving this mail because: You are on the CC list for the bug.
