Also known as the mem=nopentium bugfix.
So your AMD system keeps locking up, why not try to fix it:

Lilo users:

set "mem=nopentium" like this:

Code:
vim /etc/lilo.conf (use any editor you like - I like vim)
image=/boot/vmlinuz
label=linux
root=/dev/hda1
initrd=/boot/initrd.img
read-only
append="mem=nopentium"
if you already have something in the append line, just separate with a space.

Grub users:

set "mem=nopentium" like this:
Code:
vim /boot/grub/menu.lst
(use any editor you like - I like vim)
Code:
title=Linux
kernel (hd0,0)/boot/vmlinuz root=/dev/hda1 mem=nopentium
Now reboot and enjoy crashfree computing once again.
