Hi all
Sometime the kswap0 kernel thread jump to 25% of CPU.

I'm working on imx6dl sabresd derived board.
When this happens the "power" drop down very fast.
I have no swap partition defined and swapon gives no swap spaces are allocated.
/proc/swaps is empty.

Why kswap0 jump to 25%?
This happens when vm.swappiness is 6
Any idea?

The bsp is based on krogoth with qt5.6.1 used for QML
