This is a kernel issue specifically with vblank interrupts and also
affects acer AOA110/AOA150 models. it can be worked around with
nohz=off, disabling the hyperthreaded CPU on the atom or by saving this
to ~/.drirc to disable vblank


<driconf>
    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
        </application>
    </device>
</driconf>
