During internal review I wondered why this is a "BUG" rather than a "FEATURE" bit. Apparently, the suggestion for "BUG" came from earlier community discussions. Historically it may have seemed reasonable to say that a cache cannot span NUMA domains. But with more and more things moving off the motherboard and into the socket, this doesn't seem too weird now. -Tony
