help
Write kernel log output directly to a serial port.
+ Where implemented, output goes to the framebuffer as well.
+ PROM console functionality on Sun 3x is not affected by this option.
+
+ Pass "earlyprintk" on the kernel command line to get a
+ boot console.
This is useful for kernel debugging when your machine crashes very
- early before the console code is initialized.
+ early, i.e. before the normal console driver is loaded.
You should normally say N here, unless you want to debug such a crash.
