OK, so ownership is changed to ACPI. > What else register do you suggest me to compare? The PADCFG2 is invalid It's fine APL does not have PADCFG2. Hmm, I don't understand how this can work in Windows either. The Windows people told me that they don't save and restore anything else than padcfg registers + ie. If the ownership is changed to ACPI it means you don't get interrupts anymore (only GPEs) and that applies to Windows as well.
