This is the same AGP 'bug' for which AMD issued a Win2k patch and this 'bug' exists in the Linux 2.4 kernel series unless the kernel has been built for Athlon optimization. I may be be mistaken but do you not build your kernel, Tom? At any rate there are numerous threads on the kernel mailing list regarding this issue when AGP is used and the always recommended solution is to use mem=nopentium. In support of my position see: http://www.kickassgear.com/athlon-linux%20bug.htm If others are desired just do a google-linux search for mem=nopentium. I currently use mem=nopentium on my systems and can confirm that without this option random X lock-ups will occur if using the Nvidia driver, and on systems with the ATI Rage128 using either the ati or r128 driver if DRI is used. Even should men=nopentium be only a placebo I'll still take my medicine.
