I don't think so. Sashiko had identified that this path of cold reset won't be actually reached in the probe. I asked the introduction of a fault-inject test case so we can ensure that we do hit this case. > > Chris? André? Can you please help review so we can merge it? That aside, after we ensure the path is hit, we want to keep this cold reset one. So, the ack is already welcomed and needed. Thanks, Rodrigo. > > Raag
