不用 patch 就可以修正了

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.

而且這個應該不算是"大"bug吧...
至少不是啥安全性的 hole
