do we know if 7.4 is good for new AMD cpus? More specifically for virtualization. Historically there were some issues and things like AMD's IOMMU & similar were not exactly perfectly supported by HW vendors, UEFI/bios <=> kernel. I'm thinking of getting one and I wonder if it might be too soon. I wonder if above things are at least in an acceptable shape of older Opteron platform, and not worse. Any experience? b.w. L.
