--- Comment #2 from Michael Laß <bevan@bi-co.net> ---
I started experimenting on an entirely different system with a fresh
installation and there seems to be another key factor to reproduce this: geli
needs to use software crypto and not null crypto. To reproduce it on a system
that supports AESNI I need to specify "-e camellia-cbc".

In summary:
* never reproducible with "-e null"
* reproducible with "-e aes" and "-e aes-cbc" only on systems without AESNI
* always reproducible with "-e camellia-cbc"

So this might not even be an issue with dumpfs but with the software crypto in
geli.
