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,
