You can also try to disable acpi and see if you can keep it working. kernel parameters come to mind are acpi=off and pci=noacpi. The first one completely disables acpi and the latter AFAIR just disables acpi routing for pci subsystem. Look at kernel-parameters in linux Doc for more combinations. -- Fatih
