I am in much the same situation as you (want to deploy Epyc, waiting for SM stuff to become available). I currently have here a set of parts to make a test Ryzen box, so you are ahead of me on that though. Should have that gong this week I hope. Are you running the latest STABLE ? There were some patches for Ryzen which went in I belive, and might affect te stability. Specificly the chnages to stop it locking up when executing code in the top page ? I'll get back to you when I have done some more testing... -pete.
