Just like that. Without even looking. So no, I don't think adding a warning for this one case makes sense. If you want to add a warning yourself, you can put it in rc.local using userspace goodies like msr-tools. With them you can toggle that bit ad absurdum - no need for the kernel except msr.ko. -- Regards/Gruss, Boris. Sent from a fat crate under my desk. Formatting is fine. --
