Because of just that - you can't mix geom_part and geom_mbr because
they do the same thing, and gpart is the utility for interfacing with
geom_part.

This almost certainly indicates a problem somewhere else, not in
geom_part. You need to provide more details: what kernel messages do
you get when geom_mbr is not loaded?
