I was recording videos in 720p with device overclocked to 250-805 or 250-900. After some time of recording I noticed an intense lag and stuttering on the screen or even video preview blackout. Example result video (unplayable - tried totem and vlc) is available here: http://ubuntuone.com/12RP2T8anMerGo7AXwNkd6

Why is it happening? Using kp52, cssu thumb (iirc 8.2 - latest). Video was saved to emmc, swap on mmc1. Swappolube swappiness modifiers applied. No speedpatch nor batterypatch.

Output of `dpkg -l | grep ^ii` attached
