I'm having more serious problems. My server crashes every few days with a kernel OOPS (page_alloc:117). And this is even if I don't use any OpenGL applications. Still, I expect all of these problems could be related. There has been some discussion of this crash on the web but no solution proposed. I think there is some relation to the problems reported here since all have AMD/AGP/NVIDIA in common.
Has anyone tried using the following hint
on a 2.4.18 kernel?
