RHEL6 USB and network issue

Motherboard = Gigabyte GA-990FXA-UD3
OS = RHEL 6 workstation 64 bit

PROBLEM 1: When I have the USB keyboard and mouse plugged into any USB2 port, they do not work and RHEL6 says:

device descriptor read/64, error -32

When I plug the keyboard into the USB3 slot, it works normally. I need the USB2 ports to work. I get the same thing when I try a USB flash drive as well.

Another oddity is that when the keyboard and mouse are plugged into USB2 ports, they work fine in the system BIOS and on the grub screen. Once booted into the OS (even single user) I get the above message and they stop working.

PROBLEM 2: I can't get the on-board NIC to work. I have the network settings set manually and correctly as they work on my other 55 RHEL6 clients for my subnet. ifconfig shows the correct IP but no packets visible. ethtool sees a link connected, that it's gig speed, and that it's full duplex. That being said, you can't ping the system and the system can't ping out.

I usually have very good luck with Gigabyte motherboards right out of the box with RHEL6 but this one is pissing me off. I have a feeling it's a setting in the BIOS but I've tried the optimized defaults as well as just using the legacy settings instead of the UEFI settings.

Any ideas on this would be greatly appreciated.

After alot of searching I found this:

Seems like a common problem and the fix described works for ubuntu but not for RHEL. It's definitely a BIOS setting deal not behaving with redhat.

I give up and I'm replacing the board with one that I know works out of the box with RHEL.
