Note to AMD CPU users. If you are using a first generation Ryzen or ThreadRipper platform you may need to update your motherboard UEFI to make proper use of IOMMU Groups. If your motherboard manufacturer has not made an update available you may need to apply an ACS override patch. Successive AMD CPU platforms are unaffected.
