9/5 PA 4.6 Beta1 working great. I looked into the possible GPS issue and Google Maps was showing my location way off and would keep changing, quickly bouncing around the map from Columbia County, to Greene County, to Rensellaer County, then back to Greene even though I was sitting on my couch in Columbia County. I restored a stock backup and went in to Maps and it showed my location exactly where I was. So I reinstalled my PA backup and went back to Maps and it showed my location exactly where I was. So, I suggest restoring stock, letting it find your location, then install PA.
Edit: still reboots when trying to change GPU governor.
