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.
