Most events have the name of the system in it (see the sched events). That's to prevent the duplicates in other places. Also, in the trace output, only the event name is shown and not the system. That is, if you have more than one "hotplug_event" enabled, the trace will not differentiate them. My suggestion is the "pci_hp_event" as it will be more obvious in the trace output. -- Steve
