Ok, first things first, this line 971 points to the code *without* my big debugging patch. Is that correct? With my patch that line should be 999 because of the debugging output and other changes. Because if so, please run with it because it has a fix for the patch matching steppings too. And then send me the whole serial log because it'll have debug info for me to stare at. Thanks a lot! -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
