Intel Reboot Issues With Meltdown-Spectre Patches Rev. 2.0

Intel Reboot Issues With Meltdown-Spectre Patches

The efforts to mitigate the threat of the Meltdown and Spectre exploits appears to be WORSE than the threat itself. Intel has just admitted that some Intel systems were experiencing reboot issues after installing patches against Meltdown and Spectre. No shit.

Intel Reboot Issues With Meltdown-Spectre Patches

The WSJ reported that Intel was quietly asking their cloud computing customers to hold off installing those patches because “the patches have bugs of their own”. Specifically, there were three issues in the microcode patches they released.

In a blog post posted on 11 January 2018, Intel Executive Vice President and General Manager of the Intel Data Center Group, Navin Shenoy confirmed that Intel received reports of “higher system reboots” after applying those updates.

Basically, these systems were spontaneously rebooting after installing those patches. Not something you want your computer to do, never mind servers that caters to tens or hundreds of thousands of users.

He also confirmed that the affected systems were running Intel Broadwell and Intel Haswell CPUs, and that the issues affected both client (desktop, mobile, workstation) PCs, as well as data center servers.

Intel is not the first to be beset by the rush to patch Meltdown and Spectre. Microsoft recently admitted that some Windows 10 updates were bricking some AMD PCs.

 

What CPUs Are Affected By Reboot Issues? New!

All of the affected systems were running on Intel Broadwell and Intel Haswell CPUs.

We prepared the full list of affected CPUs, but it is a VERY LONG LIST, so we split them into three sections.

 

What Is Being Done?

At this time, Intel is working to “understand, diagnose and address this reboot issue“. Navin does not rule out another firmware update, stating that “If this requires a revised firmware update from Intel, we will distribute that update through the normal channels.

 

What Should YOU Do?

While Navin advised end-users to “apply updates” from system and operating system providers, Intel has been quietly asking their cloud computing customers to hold off installing those patches.

There has been no actual recorded threat or attack using the Meltdown or Spectre exploits. Therefore, we recommend that you STOP applying any Meltdown or Spectre patches, if you are using an Intel Broadwell or Intel Haswell system.
