add:

I can control brightness but the OSD does not work properly:
Try booting with the "acpi=off" kernel parameter
Try booting with "pci=noacpi"

OSD works and I can reduce brightness:
Try booting with "noapic"

Did not boot:
Try booting with "acpi=ht"
Try booting with "acpi=noirq"
Try booting with "pnpacpi=off"
