Hmm i guess we need to reproduce it somehow. Maybe automatic suspend resume 
cycles using rtc alarm could reproduce it - but IIRC i tried it and had no 

Btw i have been for some time running 3.7 kernel with debugfs mounted - maybe 
there is some different timing so that this problem is inhibited. You can try
