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
