Yes, agreed. And more: I'm still trying to understand why a test case like that is relevant and needs to be fixed at all. Let me re-formulate the question: what real world scenario(s) does the case of hibernating _while_ off- and onlining cores cover? Or are you simply doing kernel resiliency testing and thought that offlining cores while hibernating might make sense?
IOW, I still fail to see a strong reason for this needing fixing.
Thanks.
