I’ve been getting a little frustrated of late with this. Mainly because of turnaround times in rebuilding the kernel etc. I was looking at the kernel sources and sticking in printks here and there to try and make things clearer for me. But the time it took to rebuild the kernel, reinstall it, reboot it and grep for my lines was/is killing me. Plus, if I break the kernel I gotta go back to my working one and do it right this time. It was really difficult to make any progress so I started looking for other ways.
