Microsoft Windows XP SP3 cripples some AMD based PCs
Installing Windows XP Service Pack 3 sends some PCs into an endless series of reboots, according to posts to a Microsoft support forum. Jesper Johansson, a former program manager for security policy at Microsoft and a prominent Windows blogger, has worked with users to tentatively identify the problem as involving only machines using processors from Advanced Micro Devices.
According to Johansson, there appear to be two separate issues. One affects only AMD-equipped PCs sold by Hewlett-Packard. “The problem is that HP, apparently along with other OEMs, deploys the same image to Intel-based computers that they do to AMD-based computers,” said Johansson. “Because the image for both Intel and AMD is the same all have the intelppm.sys driver installed and running. That driver provides power management on Intel-based computers. On an AMD-based computer, amdk8.sys provides the same functionality.” Running the “intelppm.sys” driver on an AMD-powered PC isn’t normally an issue, but on the first reboot after a service pack installation, it causes “a big problem,” Johansson said. The machine either fails to boot or crashes and immediately reboots.
