Well, are you confident that your hardware-poison changes in v2.6.33 will not have any user triggerable bugs? It's a pretty silly question IMO because you can never be 100% confident. What matters is for the changes to be sane and clean, for there to be no known regression and for any reported bugs to be fixed speedily. Which Frederic is doing in an utmost excellent way ...
