Comment 39 for bug 132403

I doubt that marking the whole bug as invalid is the way to go. A BIOS update might have solved PetriL's problem although he seems to be the only one because forums are full of people missing speedstep with overclocked Intel cpu's. My E6600 is well supported from my motherboard's BIOS and works overclocked with EIST/C1E under Windows, while Linux refuses to enable speedstep.

Also note that other bugs (e.g. #213119 or #175310) are marked as duplicate of this one and this bug is marked invalid now. I believe the problem still exists and lies within the upstream kernel as there was some discussion on LKML before (can't find it anymore, sorry) and kernel developers stated they don't care about overclocking so noone tried to fix it. Ubuntu on the other hand is a distribution with a huge base of desktop users and we do overclock our hardware sometimes.
