Heiko, I'm seeing these warnings, and I can reproduce in a local build. But I have to note that its just one more of an already existing string of similar failures. I don't see anything like this on x86, not have I had robot reports for other architectures. As such, I'm considering this a pre-existing s390 issue. Please let me know if this is something you want me to look at nevertheless.
