I will try also to upgrade the BIOS, but until then I don't have access to the server.
Hi, I success to upgrade the BIOS remote with flashrom. After upgrading BIOS from 1208 to 1708 the problem was fixed. So for others who has same problems with IOMMU try to upgrade the BIOS that may fix this problem. Best regards.
