"many Athlon and Duron CPUs experience memory corruption when extended paging is used in conjunction with AGP. And, this problem hits us because Linux 2.4 kernels compiled with a Pentium-Classic or higher Processor family kernel configuration setting will automatically take advantage of extended paging (for kernel hackers out there, this is the X86_FEATURE_PSE constant defined in include/asm-i386/cpufeature.h.)" this explain why I used to have lookups when I use nvidia card with AGP enable. I had to disable AGP Maybe MandrakeSoft should add the solution in the errata page : "If you have been experiencing lockups on your Athlon, Duron or Athlon MP system when using AGP video, try passing the mem=nopentium option to your kernel (using GRUB or LILO) at boot-time. This tells Linux to go back to using 4K pages, avoiding this CPU bug. In addition, it should also be possible to avoid this problem by not using AGP on affected systems." -- http://perso.wanadoo.fr/linux_wizard/index.html - Let the data structure the program. - The Elements of Programming Style (Kernighan & Plaugher)
