It is literally the kernel ring buffer output,
so I really can not understand your question.

This I have already written, here's once more for you,
<quote>
 This noise is induced via userspace, xfce4-netload-plugin,
 http://goodies.xfce.org/projects/panel-plugins/xfce4-netload-plugin

 $ grep -i device .config/xfce4/panel/netload-16.rc
 Network_Device=enp3s0

 $ ethtool -i enp3s0 | grep driver
 driver: r8169
</quote>

Therefore, to try to reproduce this issue, 'xfce4-netload-plugin' must run within 'xfce4-panel',
moreover 'xfce4-netload-plugin' must be configured to monitor affected network interface.

No command line this time, hombre.

If you are eager to test it,
