    According to the gpart(8) manpage, the invocation is correct. It'd
be interesting to see what the log displayed yields, but before then
have you tried kern.geom.debugflags=16? I did a quick scan of
lib/libgeom and sys/geom, and all of the places (minus one) that
returned EINVAL were due to incorrect sector size. What are you using
for your disk?
