24 Say Y here if you want the PCI core to spawn a new thread for
25 every PCI device that is probed. This can cause a huge
26 speedup in boot times on multiprocessor machines, and even a
27 smaller speedup on single processor machines.
28
29 But it can also cause lots of bad things to happen. A number
30 of PCI drivers cannot properly handle running in this way,
31 some will just not work properly at all, while others might
32 decide to blow up power supplies with a huge load all at once,
33 so use this option at your own risk.
34
35 It is very unwise to use this option if you are not using a
36 boot process that can handle devices being created in any
37 order. A program that can create persistent block and network
38 device names (like udev) is a good idea if you wish to use
39 this option.

41 Again, use this option at your own risk, you have been warned!
