Maybe my previous patch which moves damages to a workqueue To add some more explanations, I'm currently only testing it with a statically linked udlfb (for fbcon) as that is what I'm mainly using the device for (with otherwise headless boxes). When udlfb is a module, I don't see those "schedule while atomic" messages (I don't know why), but having a console only after the modules got loaded isn't always an option.
