This bit will be set sometimes, if I am not clearing this bit, it will be set all the time(From the debug info I can get). I refer some code on the internet, it just clear this bit if it is set, no other operations. So I add this part code for my patch. Actually it is better to add it. Anyway, letting this setting bit go also works.
