But on Intel platforms the trigger "kicks" the patrol scrubber in the memory controller to access the address. So the error is triggered not by an access from the core, but by internal memory controller access. This results in a different error signature (for an uncorrected error injection it will be a UCNA or SRAO in Intel acronym-speak). -Tony
