It's useful to me.

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.)
