Well I have a little success story. One of the motherboards that is listed as bad hardware is working perfectly with my setup. I'm running on the Asus K8V motherboard with an AMD64 3400 CPU. A Nvidia 6600GT, with 1.5 gb of ram.
This system is running like a dream on UI2
The only problems I am having is with basic setup issues. It is more a case of I should read the user manual more.
The K8V isn't listed, but the K8V-X is. They are different motherboards. Unfortunately, someone keeps changing/deleting content so the reasons the K8V-X is bad isn't there. When I tested Two M/B's with Hauggepauge PVR cards in both Linux and Windows, they fail to work. Put them into another asus motherboard, and they work fine in both OS's.
