IOMMU Ryzen alatt nem működik

Próbálnám működésre bírni a hardver virtualizációt egy frissen összerakott gépen, hiába van engedélyezve az IOMMU és az SVM a BIOS-ban a dmesg ezt mondja:

root@Tower:~# dmesg | grep IOM
[ 0.000000] DMAR: IOMMU disabled
[ 8.619243] AMD IOMMUv2 driver by Joerg Roedel
[ 8.619463] AMD IOMMUv2 functionality not available on this system

Valaki futott bele ilyesmibe? Amit találtam, hogy az AGESA-val van valami gebasz, ha ez igaz akkor kb. az IOMMU az új lapokon amik friss BIOS-sal jönnek nem működik....

A config lentebb: Ryzen 7 2700, Asrock B450 Pro4
