That is strange, because gentoo has exactly this in portage
as the last stable version: 2.6.35-vs2.3.0.36.32

It was not set. I followed "Installation_on_Gentoo" guide
and there is nothing about it so I did not activate it.
So I recompiled kernel and now the message changed to:

vc_unset_mapping(): No such process

Again, it is shown as the very last message when I shutdown
vserver-guest with the above mentioned options. Any idea what
this means how it could be fixed?
