Perhaps there is some register on the controller chip that affects receiving data but not sending it, and isn't getting initialized. Perhaps the controller chip thinks it is receiving bad data, and flags an error or requests a bus reset? If the resets are happening faster than the printf can run, maybe the data (generation number) changes underneath the printf, much like ps/top don't get a pure snapshot?
