           If you say Y here the resulting kernel image will include
           debugging info resulting in a larger kernel image.
+          This adds debug symbols to the kernel and modules (gcc -g), and
+          is needed if you intend to use kernel crashdump or binary object
+          tools like crash, kgdb, LKCD, gdb, etc on the kernel.
           Say Y here only if you plan to debug the kernel.
 
           If unsure, say N.
