+           Kernel Debugger for Linux written by Jeffrey Vernon
+           Merkey.  'echo j > /proc/sysrq-trigger' will activate the
+           debugger from the text based Linux Console, and the 'j'
+           character (alt-printscreen/sysrq + 'j') with MAGIC_SYSRQ
+           enabled to enter the debugger.  X is not supported.
+           This debugger is minimal and text based.  Excellent help can
+           be obtained from the debugger by typing "Help Help" or
+           "help" from the debugger command console.  If you compiled
+           MDB as a module you may need to load the debugger with
+           the 'modprobe mdb' before you can access the debugger
+           from the Linux Console.  To enable the MAGIC-SYSRQ key
+           type 'echo 1 > /proc/sys/kernel/sysrq'.

+           Reset any Console Redirection to default system settings (0)
+           when the MDB debugger is active.  The Debugger will restore
+           the redirection to the custom settings when the debugger
+           is exited.  This feature is useful on systems which by default
+           redirect printk output and the screen debugger output to a log
+           file or system device, which can prevent the debugger screen from
+           being visible.  Enabling this feature does not affect or disable
+           remote operations via serial port.  It is recommended to enable
+           this feature by default if intensive debugging is intended for
+           the target system.
