I feel pretty strongly that we should handle fpswa faults the same way as unaligned faults. Given that we rate limit the unaligned faults, I'd prefer to rate limit fpswa as well. Of course, if you think you'd want to debug more than 5 faults at a time, you could change the tuning parameters (allowing for longer bursts, while keeping the logging rate the same). --david
