Right, and the fact that the kernel overwrites it still feels kinda wrong: the kernel knows where setup_data is - the address is in the setup header so *actually*, it should take care of not to clobber it. But hpa would correct me if I'm missing an aspect about whose responsibility it is to do what here... Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
