"Kernel GNU debugger, kgdb
"The kgdb developed initially as a patch is now included in the official 2.6.26 kernel. This source level debugging tool is much easier to use. It requires two machines to be connected via a serial connection (a RS-232 interface using null modem/a UDP/IP networking protocol). The gdb is used along with kgdb to trace through kernel code. The gdb runs on the host machine and the kgdb patched kernel runs on the target machine.

"GNU debugger, gdb
"This is also a powerful stand alone tool used for debugging. But with this tool you can’t set the breakpoint or trace the kernel code. Instead you can use gdb to debug the core files which are dumped when an error occurs."
