Probably not very linux, but consider the case where a device is controlling a motor speed by setting its current, computed by getting its current speed and do a simple PID control. If your device crashed (due to failure of something else, for example some LED display) while the current output is pretty large, you may cause some serious damage to whatever that motor is connected to. The thing the system should be able to do is notify such error and gracefully shutdown, for example sending commands to shutdown everything else.
Although I think this can be better done by some special panic handler that performs a sjlj and notify other systems about the failure, without continuing running with the wrong output...
