Just a ping here concerning the "nVidia Corporation G73 [GeForce 7600 GS]" and AGP issues. I still have to use agpmode=0 (aka kernel parameter nouveau.agpmode=0) to avoid kernel (framebuffer) freezes when loading drm/nouveau drivers. My next task will be to get KDB working to hopefully get a backtrace. Or is it futile at this point? Using KGDB, I think stalls the serial bus and, the info I earlier collected showed nothing relevant to this or to any indication of a kernel panic. -- Roger http://rogerx.freeshell.org/
