$#%#@%#$%... You have to enable IOMMU in the BIOS before the NIC will work! I 
stumbled across this obscure little tidbit on the fedora forum:

http://forums.fedoraforum.org/showthread.php?t=295616

It triggers some nasty AMD I10 Page Faults/xhci messages during boot of the 
201508 install media, but the network comes right up, dhcp works, no more lost 
packets, etc.

I wonder if this is related to it corrupting my USB drives I plug into it? 
Drives work the first time, sync, then umount. Next time you plug them in, 
filesystem is gone?

Oh well, at least I have a network now. I'll add it to the wiki.
