Only AMD systems affected, says former Microsoft security manager

Installing SP3 sends some PCs into an endless series of reboots, according to posts to a MS support forum. Jesper Johansson, a former program manager for security policy at Microsoft Corp. and a prominent Windows blogger, has worked with users to tentatively identify the problem as involving only machines using processors from AMD
Messages from frustrated users began accumulating on the XP SP3 support newsgroup Wednesday, just a day after Microsoft release an update to the general public.
"I just installed Windows XP SP3 and after completing the processes and when the system reboots, the system cannot proceed to load the Windows," said a user identified as "Olin" in a message that kicked off a long thread. "It just displays the flash screen of Windows then after it reboots again."

Rest here

Hmm...I'm using an AMD Athlon x2...

I installed SP3 last night, cant say ive noticed much difference, though MS does say it doesnt cause major changes to the OS.

I have installed SP3 on an AMD machine and Intel and have had no problems. Infact my laptop seems much fater.

I would still wait until it comes with Auto Updates.

I have installed SP3 and it was a pain in the arse! Tried to download from windows update about 5 times and it failed every time. In the end I just got the offline installer and now am going to take the 316MB file (which came from the Microsoft site) to every computer I want SP3 on to save downloading.

Computer didn't boot properly the first couple of times after SP3 was installed but seems fine now. Just needs drive cleaning and defrag.
