All you've done is re-quoted the same information you supplied in your initial email with nothing new. Therefore, you are wasting my time, and I really can't be bothered with time wasters.
Since you seem to be totally incapable of analysing the problem correctly, and I know very little about RT kernels, there's nothing I can do here. Sorry.
