2   The Kernel command line option <code class="constant">kgdbwait</code> makes
3   kgdb wait for a debugger connection during booting of a kernel.  You
4   can only use this option if you compiled a kgdb I/O driver into the
5   kernel and you specified the I/O driver configuration as a kernel
6   command line option.  The kgdbwait parameter should always follow the
7   configuration parameter for the kgdb I/O driver in the kernel
8   command line else the I/O driver will not be configured prior to
9   asking the kernel to use it to wait.
10   </p><p>
11   The kernel will stop and wait as early as the I/O driver and
12   architecture allows when you use this option.  If you build the
13   kgdb I/O driver as a loadable kernel module kgdbwait will not do
14   anything.
