Hi Chris,

dmesg would be a good start.  Also, have you tried other versions
(5.5, 5.6 or 5.7 perhaps) and checked if they work?

I can offer that my i217-LM works on an older snapshot:

[weerd@pom] $ sysctl kern.version
kern.version=OpenBSD 5.7-current (GENERIC.MP) #971: Sat May  2 09:18:21 MDT 2015
    [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

[weerd@pom] $ dmesg | grep ^em0
em0 at pci0 dev 25 function 0 "Intel I217-LM" rev 0x04: msi, address 
b8:ca:3a:93:03:e8

Although I do seem to experience weird IPv6 issues now and then.  I've
tried debugging this in the past, but could never find a reliably
reproducable problem case.

Cheers,

Paul 'WEiRD' de Weerd
