I add this and kernel is builded now. At the first boot I got a panic on a gif interface. I don't need it now so I commented it out of rc.conf.local and reboot. New kernel is running with WITNESS and INVARIANT... System seems not too loaded ... I am at home and the serial console is not connected. I snapshot the KVM of the panic and attatch it to this mail for the record. Henri --- remaining of previous mail clipped --- --------------060403060808030300070706--
