Microsoft pauses AMD Spectre and Meltdown updates after systems fail to boot

The Meltdown and Spectre AMD updates from Microsoft have been put on hold after it was discovered that some AMD systems were failing to boot after the update was applied.

Microsoft issued a statement to clarify exactly what’s been happening following reports from AMD users.

Microsoft has received reports of some AMD devices getting into an unbootable state after installation of recent Windows operating system security updates. After investigating, Microsoft determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown.

To prevent AMD customers from getting into an unbootable state, Microsoft has temporarily paused sending the following Windows operating system updates to devices that have impacted AMD processors:
