Sometimes it happens while I recall reading about some of the ASUS 970 based boards having problems when IOMMU was enabled in the BIOS -- the rtl would be detected but not tx/rx packets -- fix was either disable IOMMU and/or install the newest BIOS. Not sure if that is at all applicable to Gigabyte boards, but I suspect the core bios code is largely very similar. What does "dmesg" say after you have an outage event?
