 Sure:
  $ dmesg|grep wm0
  wm0 at pci0 dev 25 function 0: 82567LM-3 LAN Controller, rev. 2
  wm0: interrupting at ioapic0 pin 20
  wm0: PCI-Express bus
  wm0: FLASH
  wm0: Ethernet address 00:1c:c0:7e:47:76
 It could probably be caused by the mainboard. When I first turn it on, it
 boots something, probably a management interface, and then goes "off" again,
 but with an LED blinking. Starting from here, it is reachable via Ethernet.
 
 Also, when I rebooted my computer and pinged it from another computer, I've
 noticed that during the boot time, the same IP address that I've used befor=
 e,
 is still active and pingable (!) and I get DUP-pings during the time NetBSD
 starts.
 
 I'd like to add point
 5) IPv6 does not work at all. Probably a consequence of the previous bug? D=
 oes
 NetBSD not initialize autoconf if it think the Interface is down?
 
 Best regards,
 Michael
