AMD users complain of SP3 re-booting
The other problem, according to Johansson, also seems to affect only AMD machines, and involves an error message indicating trouble with the PC’s BIOS. Johansson said that the ensuing recommendation to update the BIOS is “most likely not your problem,” but said that the problem may be isolated to a specific motherboard. “Possibly, it is related to computers with the ASUS A8N32-SLI Deluxe motherboard in them,” he said.
Johansson also spelled out workarounds for both problems on his blog. The HP issue can be solved by disabling the intelppm.sys driver, while the second fix requires the user to plug in a USB flash drive before booting.
