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 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
