The Inquirer reports a bug in Windows XP Service Pack 3 is giving some AMD-based a lot of trouble:
One user reported, "I just installed Windows XP SP3 and after completing the processes and when the system reboots, the system cannot proceed to load the Windows. It just displays the flash screen of Windows then after it reboots again."
Angry users have also reported that, after the installation, it is not even possible to boot in safe mode, usually the last resort before setting up a repeated forehead/screen interface.
Jesper Johansson, a former program manager for security policy at Microsoft and a well respected bogger on such things has provided some pointers as to where the problem might lie.
According to Johansson, there appears to be two separate problems. 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. "
