I believe that buildworld on 4.x still builds and installs new modules into /modules including the linux and osf1 compat modules. New modules aren't guaranteed to work on older kernels, so if your kernel is still 4.9, that is probably your problem. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
