It shouldn't hang (and it doesn't on the Itanium & Itanium 2 systems we have). Sounds like something is off... I agree that the output format is hard to understand, but a user-level tool can fix that. In my experience, the most useful value to look at is CR[19], since it contains the IIP. (It would be nice, though, to have a beginners guide to decoding MCAs until there is better tools.) --david
