"The Gigabyte GA-970A-DS3P is a ATX mainboard with AM3+ socket. The board is supported under Linux, but some additional settings are necessary to use it:
By default, the board is shipped with IOMMU deactivated in the BIOS. With such settings the USB 3.0 ports work under Linux, but the USB 2.0 and Ethernet are deactivated. If IOMMU is activated, USB 2.0 and Ethernet work under Linux, but the USB 3.0 ports are deactivated.

File /etc/default/grub 1 GRUB_CMDLINE_LINUX=«iommu=soft» The new configuration is activated by the command
1 sudo update-grub
