- If you say Y here, it will be possible to remotely debug the

- you also turn on the kernel config option
- CONFIG_FRAME_POINTER to aid in producing more reliable stack

- kernel debugger is available at http://kgdb.sourceforge.net

- This is a kgdb I/O module specifically designed to test

- intended to for the development of new kgdb stubs
- as well as regression testing the kgdb internals.
- See the drivers/misc/kgdbts.c for the details about
- the tests. The most basic of this I/O module is to boot
