Solution

There is a fix already committed to the Linux Kernel, but it has yet to make its way to the Debian version, on which the Checkmk Appliance is based.
The issue has no impact whatsoever on the appliance, so it can safely be ignored for now. Just make sure, it is the exact same error, that you are seeing.
