         | LOG_EMERG log level. This component is experimental and its
         | public interface is subject to change."
         | 
         | First step is to log something with LOG_EMERG level. Then maybe
         | make the system crash?

         | 
         | (The screen normally remains white on black. The console can as
         | well be a COM port.)
         | 
         | You can configure it to auto-reboot by putting a timeout value
         | to /proc/sys/kernel/panic.
