2  using the gdb monitor command.  You don't want to execute any of the
3  run control or breakpoint operations, because it can disrupt the
4  state of the kernel debugger.  You should be using gdb for
5  breakpoints and run control operations if you have gdb connected.
6  The more useful commands to run are things like lsmod, dmesg, ps or
7  possibly some of the memory information commands.  To see all the kdb
8  commands you can run <code class="constant">monitor help</code>.</p><p>Example:
