This is what I need for the boot process. After I'm booted I want to turn off printk() output to the serial console but keep it going to netconsole. I've been googling for an hour, how do I do this? I need to turn off the serial output after boot because serial printk() disables interrupts for up to 1ms which is enough to cause me to lose a lot of other interrupts. -- Jon Smirl jonsmirl@gmail.com
