Backup Anytime

An online backup software upgrade today turned out problematic as the clients computer entered a loop of continuous reboots.

It must have appeared from the clients point of view that this was a consequence of our upgrade. We knew however that while this seemed to start after our upgrade, the proximate cause lay elsewhere and our upgrade or more likely the restart after it facilitated a prior registry change to take effect.

Thankfully we are dealing with the client for some time so relative calm remained while we investigated the issue. About an hour later we positively identified the issue and resolution through local investigation subscription tech forums.

Here’s the beef.

This particular reboot issue is peculiar to AMD powered computers subsequent to a Windows XP service pack 3 upgrade. Blaming Microsoft code or AMD drivers will not sort anything.

This will

Boot to Safe Mode
browse to C:\Windows\System32\Drivers
select intelppm.sys and rename it to XXXintelppm.syx
Restart

Fix for the XP SP 3 Reboot difficulties

Safe Mode
regedit
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Intelppm
modify to put4 as Value Data
restart

This worked for us. If you have more to add, please do.
