   10           If you say Y here, it will be possible to remotely debug the
   11           kernel using gdb.  It is recommended but not required, that
   12           you also turn on the kernel config option
   13           CONFIG_FRAME_POINTER to aid in producing more reliable stack
   14           backtraces in the external debugger.  Documentation of
   15           kernel debugger is available at http://kgdb.sourceforge.net
   16           as well as in DocBook form in Documentation/DocBook/.  If
   17           unsure, say N.

   34           This is a kgdb I/O module specifically designed to test
   35           kgdb's internal functions.  This kgdb I/O module is
   36           intended to for the development of new kgdb stubs
   37           as well as regression testing the kgdb internals.
   38           See the drivers/misc/kgdbts.c for the details about
   39           the tests.  The most basic of this I/O module is to boot
