    Re: GIGABYTE GA-970A-DS3 motherboard not working with 64 bit kernel

    An enormous thank you to monkblah - That fixed my problem in one easy step. Now to the question - why would I not want iommu enabled, even if the motherboard would work with it disabled?

    qwertybyrd I'm very glad this helped someone! I spent countless hours struggling with it before finally stumbling into the solution with some help on these boards.

    Now I'm having a new problem actually installing ubuntu to my hard drive. Something to do with UEFI, I think. Will probably have to start another thread...

    This worked for me! Thank you SO much!

    Dude... I owe you one... I had spent hours searching and trying random bios settings... that one was down lower, so I hadn't got to it yet, was frustrated so dont know if I ever would have, lol. I was searching mainly by motherboard model, mine is GIGABYTE GA-990FXA-UD5

    I threw that it so it hopefully pops up in someones future search and saves them time as well.

    Thanks again!

    I confirm that enabling the IOMMU setting fixes USB for the GA-990FXA-UD3 Rev 3 Board. Thank you so much! Now I just need the onboard NIC to work and I'll be in heaven.

    Update: I updated my BIOS to the latest version (FC) for my board (GA-990FXA-UD3 Rev 3). I enabled IOMMU and reinstalled Ubuntu Server 12.04 64 bit. The USB and onboard NIC (Realtek 8111E) are now working. Thank you Thank you Thank you!

    Try seting IOMMU=yes on BIOS setup. All USBs and the onboard Ethernet should be fixed

    :edit:
    Turning on IMMOU let me use network/usb
    disabling uefi allowed me to install Ubuntu
    Removing a corrupt gpt on the HDD let me dual boot.

    I actually have it sorted now more or less.

    After getting this computer set-up I was having some issues with booting into Ubuntu as well, Windows 8 installed from a USB no problems.

    I have the Gigabyte 970A-DS3 Rev.3 board, I got it yesterday and it already had the latest BIOS firmware (FD if I remember right).

    USB/Network didn't work until I enabled IMMOU in the BIOS.

    So, because I've spent all day trying to get this working, I just hit install, and everything went as I expected up until boot time.

    It booted straight into Windows, I've gone into the livecd to make sure grub is installed but it just seems to ignore it no matter what I do.

    Just wondering if anybody has a solution and apologies in advance if I made any errors, it's late and I'm brain-tired.

    Thanks. I have the GA-970A-D3 (edit/correction - 970A-D3P), as well, but with a Rev. 1 PCB. I flashed the BIOS to F5 before installing 12.04 x64, but this did not resolve the problems, not that I was expecting it to as I did not yet know the problems existed. I managed to work around the issues with trial and error. What was frustrating is that problems were inconsistent. I managed to get a cheap Acer USB keyboard and a Gygabyte mouse to work on the USB 2 ports (nothing else would work at all) and all was fine for a couple of days until I took the system down off the bench, disconnecting the keyboard and mouse. Upon reconnecting everything, the keyboard and mouse stopped working unless I plugged them into the USB 3 ports. USB drives were hit and miss. Some old Kingston keys worked fine. Some newer keys did not. USB hard drives did not work at all. The NIC never worked. I had to install a old 10/100 Realtek chipset card to make a network connection.

    Enabling IOMMU in the BIOS seems to have resolved the issues - fingers crossed. One minor side effect, however, is that the system takes a few seconds longer to POST and boot now.

    Hmmm... Usually I am an Asus guy. The Gigabyte purchase was deviant behaviour on my part.

    Thanks again.

    Ga-970a-ds3p

    Enabling iommu in the bios will fix the Ethernet issue and make the usb 2.0 ports work for board GA-970A-DS3P, but usb 3.0 ports will no longer work on the back of the motherboard or from the internal 20 pin connector for the front panel.
