--- Comment #1 from Alex Deucher alexdeucher@gmail.com 2012-12-07 14:27:18 --- The error messages are just a symptom. They are generated because the driver is trying to access hardware that has been powered down. vgaswitcheroo probably needs some logic to track what state the hardware is in so that the drivers know whether it's there or not.
