It depends on what you're trying to do.  Somebody else already mentioned
the debug chapter in Linux Device Drivers, (available online at
http://www.xml.com/ldd/chapter/book/ch04.html), so I don't have to do
that...:)

The one thing I might add is that, for certain kinds of work, User-mode
Linux is seriously great stuff.  With UML, you have a kernel running as a
regular process, and you just hit it with gdb in the usual way.  Great for
things like filesystems; not so good for stuff that has to work with real
hardware.
