Yes, it is related to pressing the buttons. I suspect that it
migth have something with the frequency of the pressings, e.g.
when I do it very fast. Or maybe the connectors of the button to
bounce (not sure if this is the right english word for
german "prellen").
If I don't press buttons, the box doesn't lock up.
I need to find out if the existence of atlas_btns makes a
difference. My guess is that it shouldn't make any difference,
the atlas_btns driver doesn't do anything with the interrupt 9.
It's the ACPI subsystem that handles this interrupt, atlas_btns
just "subscribes" into it and filters out some events ...
/me going to find out
