Proxmox 4.4 & Ryzen CPUs

No it did not work on Proxmox 4.x with all updates (I try 3 days ago with a fresh / new install) . kvm/qemu not work at all. Also the same without kvm/qemu ... in 2 hour I was not able to install a linux-mint, so I abort the install.

In the logs I see somthing like ... unknown KVM module if I remember ;)
