How should i start working on kernel programming?

[Dave Arsenault]

How would I go about debugging a LKM. I am currently working on a simple
kernel module that overwrites the open() syscall and sends the output
through a parsing routine.

I've read many articles talking about using the (gdb) add-symbol-file
lkm.ko<address> and in fact that works but as far as I know I can set
breakpoints
that never break and that's pretty much it.

Thanks
