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.

Regards,

Alexander
