The hardware doesn't change between a working & not-working kernel, and somehow the PCI probing fails. Hmm, do you have CONFIG_EDAC set ? There's an outstanding bug (well, lack of feature) , where it claims the PCI device before AGP gets a chance to. This is unrelated to your hang however, but would at least explain the inconsistent probing. > Perhaps my "solution" is to remove this module completely? > I don't seem to need it. It's needed only for 3d, but it'd be good to figure out why its so broken on your system, even if you don't need it.
