>Description:
	In this snapshot there are still problems on my compaq armada E500
	with the pci routing table:
	PCI IRQ Routing Table rev. 1.0 found at 0xf0970, 
	size 0 bytes (-2 entries)
	pcibios_pir_init: bad IRQ table size

	After this it reports:

	PCI IRQ Routing Table rev. 1.0 found at 0xf9c70, 
	size 224 bytes (12 entries)
	PCI Interrupt Router at 000:07:0 (vendor 0x8086 product 0x7110)
	PCI Exclusive IRQs: 11

	Secondly: there are problems when using
	the 3Com 3C575C-TX network card in this laptop.
	When i configure it with ifconfig, i hear a loud click
	and see ex0 interrupting at 11
	Imidiatly after i see: ex0: device timeout (N times, N>3) 
	Here follows the dmesg output:

	     Result:

	     a loud click and there was echoed: ex0 interrupting at 11

	     then:
	     ex0: device timeout
	     and so on, in dmesg:
		  
	     <3>ex0: device timeout
>How-To-Repeat:
	Boot netbsd-1.5.2 or 1.5.3_RC1 on a compaq armada E500
	with 3c575c-tx network card.
>Fix:
	Dont know, however, i tried a dos config program to
	configure the card from dos.
	It reported that only irq 5 was free.
	irq 11 is shared with build in sound card and usb.

>Release-Note:
>Audit-Trail:
>Unformatted:
 		card in NetBSD-1.5.3_RC1
