An electronic apparatus includes processing devices including first circuitry, a controller including second circuitry, and a memory storing a time-out time and an extension time. The first circuitry that detects an abnormality, transmits an abnormality occurrence notification, transmits a preparation completion notification, and transmits an extension request. The second circuitry transmits a restart preparation instruction to the processing devices excluding a source of the abnormality occurrence notification, waits for the preparation completion notification until an elapse of the time-out time. The second circuitry restarts the processing devices in response to the preparation completion notification from the processing devices or the elapse of the time-out time. The second circuitry extends the time-out time by the extension time in response to the extension request and restarts the processing devices in response to the preparation completion notification or the elapse of the extension time.
