+          This is a kgdb I/O module specifically designed to test
+          kgdb's internal functions.  This kgdb I/O module is
+          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
