Using gdb to debug the kernel is not an easy trick. You will need a kgdb patch for the kernel, and 2 computers. 1 for running the

Would VMWare let you run the kernel you're debugging in a VM and
watch
it
from the host?
That is a very good question. Last time I used kgdb, it was done using
a
serial (RS232) cable. These days, I really don't know.
It can be done on certain processors, but I don't have one of them - the Pentium-D has the necessary 64 bit capability, but this is a mere P-4 - no such lock (thought of that! :-).
