Judging by the message I'm guessing the master in the system accessed something that didn't respond or the address that was used didn't exist in the system (Qsys fabric doesn't have a timeout mechanism). I would start by looking at the Qsys design and make sure the address you are attempting to access is present in the system. If you are trying to access a custom IP core then I would double check the implementation against the Avalon specification to make sure the logic is designed within spec.
