 John> Can you try this patch?  It should disable MSI on your machine:

BTW, I have the same problem with

em0 at pci2:10:0:  class=0x020000 card=0x00db0e11 chip=0x10108086 rev=0x01 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82546EB Dual Port Gigabit Ethernet Controller (Copper)'
    class    = network
    subclass = ethernet

and disabling MSI fixes it. The same for if_ipw also:

ipw0 at pci1:3:0:	class=0x028000 card=0x25618086 chip=0x10438086 rev=0x04 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801 Intel(R) PRO/Wireless 2100 LAN Card Driver'
    class    = network
