I have a feedback for the chipsets listed in the patch. The protection via the extra parameter is owned to the fact that intel recommends against the OS doing this. Quote: "SW shall not manipulate SMS during runtime operation; that is, the OS will not do this." I would not see early fixup as runtime, however, better save than sorry. Advantages are better performance and lower power consumption. I don't wanna break anybody's data with that patch, hence the precaution. Bye, Joerg
