I checked in a patch that modifies the config and documents the issue in
README.Debian. I wasn't able to test it yet, so I'm not tagging this bug
as pending.

Nevertheless, while patching I started not feeling very comfortable with
this, for the following reason: If one has InfiniBand, it will not be
working anymore, maybe without warning. To enable it again, one has to
do so on all nodes. If one doesn't have InfiniBand, all one gets is a
quite annoying warning but that doesn't influence the behavior at all.

So the question I asked myself is: Isn't it more reasonable to comment
out the configuration setting and add a line "uncomment if you want to
shut up libibverbs". This would not influence the runtime behavior at
all. Opinions?

Best regards
Manuel
