If we're using vga switcheroo, the device may be turned off and poking at it can cause an oops.
I'm unfamiliar with what actually happens here after it is turned off. Can you post an OOPS for an example?
The device will be in D3, so I'm guessing we read back some register and get 0xFFFFFFFF, and later fail.
That's sounds reasonable. A bit of explanation does wonders if I (or anyone else reading through the history *or* code) ever encounter similar bug reports.
Is anyone else concerned by the acpi_lid_notifier never being decoupled when the module is unloaded? And the randomness of int_lvds_connector?
I love our code, every time you read it you find another bug. -Chris
