As this interrupt is just for development purposes, as the TRM says, and the sheer amount of interrupts fired can seriously disrupt userspace when testing the lower frequencies supported by the EMC. From the TRM: "There is one performance warning type interrupt: ARBITRATION_EMEM. It fires when the MC detects that a request has been pending in the Row Sorter long enough to hit the DEADLOCK_PREVENTION_SLACK_THRESHOLD. In addition to true performance problems, this interrupt may fire in situations such as clock-change where the EMC backpressures pending traffic for long periods of time. This interrupt helps developers identify and debug performance issues and configuration issues."
