Hi, I have a new motherboard, a Gigabyte 970A-D3, "Ultra Durable", Rev 3.0. I want to get Ubuntu working on it, but so far, usb and networking don't work.
I've tried booting four different distros from live CDs to test. Here are the results:
==============================================
Knoppix 7.03: Kernel 3.4.4 #14 SMP PREEMPT. USB and networking work ok.
MarBSD 5.2: Kernel openBSD livecd.my.domain 5.2 GENERIC.MP#368 amd64. USB and networking work ok.
Xubuntu 12.10. Kernel 3.5.0.17-generic #28-Ubuntu SMP x86-64. USB and networking
DO NOT WORK.
S
ystem Rescue CD 3.1.1. Kernel 3.2.33-std311-amd64. USB and networking
DO NOT WORK.
==============================================
So presumably the hardware is all right since it works with two of the four distros.
Also note that one of the failing distros kernel is newer than one of the succeeding ones.
Networking (wired ethernet) and USB are both built into the motherboard. Tested with two known-good USB devices in several ports, and a known-good network cable.
Can someone advise me on what is going on? Why does ubuntu fail and how can I get it to work?
I used to have a previous Revision of the motherboard with a different bios that worked with ubuntu. The new bios has UEFI and other new stuff, could that be somehow related? Maybe I need to change something in the bios, but I would have no idea what.
Or is it that the system's interrupts are somehow interfering with each other? But why for ubuntu but not old Knoppix?
Here are some of the messages I get from the logs with the failing distros:
Trying to connect a usb device:

Many NetworkManager errors. Normally it just connects to my network with DHCP:
