They have had some hard failures of 11/23 CPUs. For instance, on a configuration which runs both RT-11 and diagnostics, booting up Unix causes the system to hang. The run light goes out, but the system does not go into ODT. The solution was to swap in a new 11/23 CPU; then everything was okay. This has happened several times. They send the CPU back, who sends them a new one. Sometimes the replacement works, sometimes it doesn't. Has this happened to anyone else?
