igb + I350-T2 Offline Test Fails with Linux 2.6.33

I am evaluating the Ethernet Server Adapter I350-T2 to replace our previous end of life card. I have not had any issues with the card during my operational tests but when I execute the cards offline tests the network interface goes offline and requires the network service to be restarted. My concern that there is some real instability between my hardware/software and the I350 that could manifest in failures over prolonged use.

Here are my test results and kernel log data.

$ sudo ethtool --test eth2 offline

Cannot get strings: No such device

Why is this offline test failing? Should I even worry that this test fails? Does anybody have some tips as to what I should change/fix/do to get the test to pass?

Thanks,

Stephan
