As we're basically talking about two types of vulnerability here, I seem to remember that one of them also affects "old enough" CPUs from the Pentium 4 era (before Core), in other words, when "HyperThreading" or "HT Technology" arrived in Intel chips. But I'm not convenced that I remember correctly. Further investigation should help. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
