Well I also updated to Beta 16.B10 and seem to have a problem. System steps thro until it shows a "52" on the internal display and I just have the big truck on the screen. Can't get to the Bios setup to raise voltages, etc.

Sometimes with the previous bios I had it freeze for a minute or two on boot, at the same point, but that problem had gone away. Now it's back and currently it's a LOT longer than 2 minutes...
