-          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 cannot 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 persistent 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.
