$#%#@%#$%... You have to enable IOMMU in the BIOS before the NIC will

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.
Blame Gigabyte, the only reason to disable IOMMU is if you run a 32-bit OS .
On all x86_64 OSes running with IOMMU disabled will degrade graphics
performance A LOT.
As you found , disabling IOMMU also affects other hardware badly.
TL;DR :
64-bit OS >>> ENABLE IOMMU
