           This allows device drivers to enable MSI (Message Signaled
           Interrupts).  Message Signaled Interrupts enable a device to
           generate an interrupt using an inbound Memory Write on its
           PCI bus instead of asserting a device IRQ pin.
 
+          Use of PCI MSI interrupts can be disabled at kernel boot time
+          by using the 'pci=nomsi' option.  This disables MSI for the

+       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.
 
-         This feature has been deprecated as of v2.5.53, in favor of using the 
-         tool lspci(8). This feature may be removed at a future date. 
+         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.
 
-         lspci can provide the same data, as well as much more. lspci is a part of
-         the pci-utils package, which should be installed by your distribution. 
-         See <file:Documentation/Changes> for information on where to get the latest
-         version. 
+         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!
