Kernel debugging I would like to study the flow of some linux device drivers and some minimal flow of kernel (threading cum context switching and interrupt management). How can I debug the linux kernel? What are the basic steps for doing that? Recently i successfully compiled and integrated new kernel (2.6.34.7) into my machine running the 2.6.29 kernel.

It depends on what you really need. Probably simple `printk()` function is gonna be OK for the beginning. There is also the `/proc` interface you can use to get useful information from kernel.

If you need something more complicated, use KGDB (kernel debugger).
