I digged into it a little bit more. The machine I'm using is a quad-socket machine with four Intel X7560 processors. X7560 is a Nehalem-EX processor. As pfmon runs fine on another Nehalem machine I've tested, does that mean that pfmon is broken for Nehalem-EX processors? Any clues on how to go about fixing this?
