Sorry I don't know either, I find it by reading code, this time. It is really necessary to continue analyzing why. In 2nd half of 2013, I have planned to make some patches outside kernel but related with kernel (e.g. LTP, gcc patches). This kind of issue is a good chance for me to start in 2nd half of 2013 (start from next month). So if no others reply for it, I will start analyzing it in the next month, and plan to finish within a month (before 2013-07-31). Welcome additional suggestions or completions.
