I'd like to report that we're running into this issue also, in our case
on systems that are based on the Intel S5520UR Server Board, running
8.1-RELEASE. If the ichwd driver is loaded we see the same messages,
and network communication via the igb nics is non-functional.
Have you had any luck?
Thanks,
Charles
