I guess we need to run Vista on them to find out how they behave. What OSI strings did your KVM setup expose? We know that Windows changes behaviour under various circumstances depending on which OS the firmware requests, so it's almost possible that this is another of those cases. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
