There clearly seems to be a bug at least in freebsd 11.0. It has to do with
the swap file. What I forgot to mention in my earlier post was that
 ​I dont have a swap partition since I just put the freebsd root over the
ubuntu partition. And I had created a
swap file based on the  instructions in 11.12.2 Creating a swap file.

I got a clue from the freebsd-forums:

If the link is down (for some reason, I see the server is down quite often
these days), use the below cached link:

So, I just did a swapoff -La and then ran the split command again - no
issues whatsover!

I will raise a bug report -- and try to support with logs if needed.
