[ Or maybe my memory confused it for the facility used by powertop to keep track of causes of CPU wake-ups? ] In any case, I have a machine here whose disk keeps spinning back up on a regular basis, and I can't seem to find any correlated event. Is there a tool that can help me track down the reason why the disk is accessed?
