+ 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.
