I was not aware that there was a problem. cp .config and make oldconfig should be sufficient -- and I don't understand why you would need to hit enter many times. I repeated this on my system without having to answer any oldconfig prompts and still got build errors. There is no secret that I know of, but it would be good to get to the bottom of this problem. -- ~Randy
