Hello, Thanks for the patch, but I would prefer a single one for the region quirk and you will recive the credits when this will be in kernel :) Hmm it seems you have ACPI PNP that will put correct IO regions to /proc/ioports, Please try booting without the quirk patch with pnpacpi=off and then cat /proc/ioports and then with same kernel option but with the quirk patch. Thanks Regards Rudolf
