That said, there still isn't any AMD documentation around the microcode updates that I've been able to find, so I have no idea what the correct patch level is even supposed to be. I just know that I'm not getting a message about early updates. I do have linux 4.4.13 which includes the family 17h patch. The other odd thing is that a firmware update was released for my motherboard (ASRock AB350 Pro4) on the 10th, and if I flash it grub will no longer boot the linux kernel, and it is pretty slow overall, but it will still boot memtestx86 just fine. I figured I'd wait a few days and see if there is any further info on it. -- Rich
