I was thinking about this today because typically intelppm.sys does not change very often. In the past year, Microsoft did update intelppm.sys for
Penryn 45nm Deep Power Down support. I wonder if you loaded KB
940566 on an OEM XP SP2 build, if you would experience the same crash issue.
If you don't know what I am talking about, read
here and
here about the AMD CPU issues on some OEM XP builds that mistakenly include intelppm.sys in their deployment build.
Does it change anything overall? Not really, but I am always curious about stuff like this.
