Re: BSOD with 6111
AFAIK opteron-boards always need the agpgart?
Maybe you should try and build and own kernel form kernel.org sources and spend extra time on the agp-config-options?
I think, you should built the module into the kernel, but I am not sure. (Yeah, I know, on ia32, they tell us, to make it a modules, but if I remember right, it is better to built it in on opterons/amd64)
