Ok I have replaced files in /rcS.d/ built kernel 3.7.10 and it all works 
ok as expected. I then ran make oldconfig on 3.8.2 kernel I get the 
error back, I then just added .config to 3.8.2 kernel and ran menuconfig 
"silentconfig" then make and I end up with the errors. So the error 
looks like a  kernel problem,
