Another nifty kernel debugging tool; if you don't have another machine
to spare and want to debug your OWN running kernel try kdebug:
ftp://hyper.stanford.edu/pub/pcmcia/extras/kdebug-1.6.tar.gz
issues some commands to gdb for limited debugging (no single-stepping
or breakpoints, or course, but viewing AND modification of kernel structures
is available indeed!).
BTW, try using ddd with the kdebug gdb, and you'll be able to graphically
view structures and pointers inside the kernel. Very cool.
