There's kdebug which is very convenient if you want to change
variables in the running kernel. The kernel must not even be compiled
in debug mode!

However, it's not a real debugger. For this, you need 2 computers,
connected by a null modem cable, and a patch named gdb-stub. Look
at the online version of the Kernel Hacker's Guide

and look for gdb-stub
