It depends on if the first access is a read or a write. If it's a read (and odds are good that's true), we will get the exact IP that faulted and get something about "CPU timeout" in the PIM dump. > Of course, this is a machine with CCIO, so it could be something going > wrong with the CCIO programming too. But I think it's Dino. I doubt it too. I agree it's much more likely something with Dino. thanks, grant
