Re: em0: Unable to locate IO BAR ( two 82542 cards )

I'm having this same issue (well, identical symptoms) with an 82534. Did you
get the fix finished?

Tryed with up to date current and two months old, same result.

#pciconf -l -v
...
em0_at_pci3:4:0:   class=0x020000 card=0x10048086 chip=0x10048086 rev=0x02
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82543GC Gigabit Ethernet Controller (Copper)'
    class      = network
    subclass   = ethernet
...

#dmesg
