It is not going away in my case either, like with Andreas test.
I tracked down every command I issues and since Jan reported that it reproduces
in a clean VM for him I'd ask to also report every command used including setup
so we can find where things differ.
I only got this:
$ dmesg | grep rx
[ 229.924109] rdma_rxe: loaded
[ 302.214732] infiniband rxe0: set active
[ 302.214735] infiniband rxe0: added ens3
So we might wonder about your log in regard to:
[ 989.823540] rdma_rxe: already configured on enp0s3
[ 1074.929240] rdma_rxe: unloaded
And also in your log:
rdma-ndd[5699]: set Node Description failed on rxe0
That does not seem like a clean guest, something happened before here.
Do you have an idea what that might be?
Your log also contains quite a bunch of Desktop related warnings on
dbus, would you mind on a retry to use a server image which comes with
much less clutter for testing rdma?
