Are the results any different when using the GENERIC kernel? I have
had a similar issue when running a stripped down kernal without any
modules built or loaded. I never was able to discover the necessary
module that needed to be present for a successful ntp when compiling
the system source without building all of the modules. I am also
running FreeBSD 9.1 on an amd64 system.
