+       help
+         Say Y here if you want the PCI core to spawn a new thread for
+         every PCI device that is probed.  This can cause a huge
+         speedup in boot times on multiprocessor machines, and even a
+         smaller speedup on single processor machines.
+
+         But it can also cause lots of bad things to happen.  A number
+         of PCI drivers can not properly handle running in this way,
+         some will just not work properly at all, while others might
+         decide to blow up power supplies with a huge load all at once,
+         so use this option at your own risk.
+
+         It is very unwise to use this option if you are not using a
+         boot process that can handle devices being created in any
+         order.  A program that can create persistant block and network
+         device names (like udev) is a good idea if you wish to use
+         this option.
+
+         Again, use this option at your own risk, you have been warned!
+
+         When in doubt, say N.
