I posted the following on the bug: 2.6.32 is over 5 years old (Dec 2009). I suspect this bug is in the old FRTO code that Yuchung removed when he rewrote FRTO from scratch in 2013. Can you please test a newer version of the kernel (preferably 3.19 but at least 3.12 or newer) to see if this bug is still around? Thanks! neal
