6 | Write kernel log output directly into the ocd or to a serial port. | |

8 | This is useful for kernel debugging when your machine crashes very | |
9 | early before the console code is initialized. For normal operation | |
10 | it is not recommended because it looks ugly and doesn't cooperate | |
11 | with klogd/syslogd or the X server. You should normally N here, | |
12 | unless you want to debug such a crash. | |

19 | Say Y here to include definitions of printascii, printch, printhex | |
20 | in the kernel. This is helpful if you are debugging code that | |
21 | executes before the console is initialized. | |

28 | Say Y here if you want the debug print routines to direct their | |
