           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
+          entire system.
