Are you sure you're using the latest BIOS for your motherboard? Can you check for updates and if you get a newer version, can you update your BIOS and do the two commands above? If there's no newer BIOS, we can try applying the workaround at boot in an init script to fix your issue. -- Regards/Gruss, Boris.
