	Although interrupt sharing is allowed for PCI devices, some
	devices do not function well when they share an interrupt with
	a dissimilar PCI device. Try changing the IRQ assigned to the
	Ethernet controller or the other device. For example, for
	NetWare Versions 3 and 4 it is recommended that disk
	controllers not share interrupts with LAN controllers.
	• Make sure that you are using the most recent device driver
	available from the World Wide Web.
