This has been brought up before for a different board, none specifically
mentioned this one nor the if_em driver (it was if_igb before on a X8DTU-6+
board).

While I'd love to try out some fixes myself however I don't have a ton of
time with this system in my hands to be developed on. Jack (as referenced
in the kernel pr) felt that it was too few system specific to go further
with the issue as per the last response.

I would be more than happy to assist or even lend remote access to this
machine to figure out just what's causing the problem if anyone is up for
the task, but I will only have about 3-4 days with it. I have confirmed
dumping msix on the boot loader will permit the system to boot up and
function, however horridly slow (6gbps drives pushing 8mbyte/sec isnt even
usable). Maybe there's a grander problem here.. with supermicro? Let me
know, I'll happily test whatever if it benefits the community.
