I had a similar issue. Just bought a new MoBo, processor and ram. GA- 990FXA-UD5, AMD FX8350 and 8 GB Kingston Hyper Beast DDR3 2400 Ram. After Adjusting the RAM voltage to 1.65 Volts I installed an old HDD I had from a previous build. It was used on an old Intel P4 32 Bit Dual core MoBo. Dual boot with dual drives. XP on one drive and Ubuntu 14.04 - 32 bit on the other. When booting off the Ubuntu 32 bit drive everthing was fine. Windows XP of course flipped out and crashed. (Not unexpected). Now I have a 8 Core 64 Bit processor running a 32 Bit OS. Obviously this was a little disappointing. When I tried to boot Ubuntu 14.04 - 64 Bit version, well that's when life got interesting. It would boot sometime but always lost USB and LAN ports..
Since windows was toast anyhow I wiped it an loaded Ubuntu 64 Bit on another system to get it installed. Now I have 2 identical drive, one with Ubuntu 32 Bit OS and the Other with the 64 Bit version. The 32 Bit version worked fine, but everytime I tried 64 Bit OS - no joy. I stubled another post with a similar issue and found a solution that worked. In the BIOS there is a default for IOMMU (Disabled), when I enabled the IOMMU suddenly the 64 Bit OS worked. USB 3.0, Gigabit LAN. Life is good again. Now back to the drawing board to see if I can stripe the drives since both drive are older and slower. See if I can squeeze a little more speed out of them. I hope this helps.
