I googled and found something where the developer talks about to
enable "lapic" at boottime. Cyrill Gorcunov  wrote a patch for this
warning, when lapic is not enabled at boottime, this should already
fix this warning.
I have set this now, but I will reboot later to find out, if the this
warning will be gone with this boot option.
