How do I enable/disable all debug messages when the kernel is booting up? From my limited understanding I have to change the DEFAULT_MESSAGE_LOGLEVEL, DEFAULT_CONSOLE_LOGLEVEL and MINIMUM_CONSOLE_LOGLEVEL in kernel/printk.c however I'm unsure what each one does. My kernel currently doesn't boot up properly, either hanging there or getting a kernel panic and I'd like to know where it fails. Do I simply set all 3 to 7(KERN_DEBUG) and rebuild?


edit: nvm got it to work by changing all 3 values to 7.
