Rex · ‎23.01.2018

Intel hat auf seiner Security Center Website bekannt gegeben, dass die Ursache für die Probleme (Reboots) für die Broadwell- und Haswell-Plattformen identifiziert worden ist und rät davon ab, die zuvor bereitgestellten CPU-Microcode-Updates einzuspielen. Es wird neue Updates geben, die die Probleme mit den alten Updates beheben.

Recommendations:
Updated Jan. 22
We have now identified the root cause of the reboot issue impacting Broadwell and Haswell platforms, and made good progress in developing a solution to address it. Based on this, we are updating our guidance for customers and partners:

We recommend that OEMs, Cloud service providers, system manufacturers, software vendors and end users stop deployment of current versions on the below platforms, as they may introduce higher than expected reboots and other unpredictable system behavior.

We also ask that our industry partners focus efforts on testing early versions of the updated solution for Broadwell and Haswell we started rolling out this weekend, so we can accelerate its release. We expect to share more details on timing later this week.

For those concerned about system stability while we finalize the updated solutions, we are also working with our OEM partners on the option to utilize a previous version of microcode that does not display these issues, but removes the Variant 2 (Spectre) mitigations. This would be delivered via a BIOS update, and would not impact mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown).

We believe it is important for OEMs and our customers to follow this guidance for all of the specified platforms listed below, as they may demonstrate higher than expected reboots and unpredictable system behavior.
The progress we have made in identifying a root cause for Haswell and Broadwell will help us address issues on other platforms. Please be assured we are working quickly to address these issues.

Wir folgen der Empfehlung von Intel und stoppen die Bereitstellung aktueller Versionen, da dies zu unerwartet hohen Neustarts und unerwartetem Systemverhalten führen kann!
