Symptoms

MCE Log Errors

You may find reports or logs of MCE errors indicating Intel hardware platform is not recognized or valid. This is a known condition of running MCE on un-supported platforms. Currently MCE logs are compatible with chipset generations up to the Skylake and these errors can be expected on the KabyLake generation of processors.

To check compatibility of MCELog tool with your hardware platform:

  1. In Root Terminal Execute: $ mcelog –help

    This command will return an output of all available commands followed with a list of "Valid CPU’s"

  2. Next run the command: $ mcelog –is-cpu-supported

    This command will return a list of valid CPU generations. If the hardware is not supported you may see other outputs such as:

    • "Mcelog: Family 6 Model 9e CPU: only decoding architectural errors"

Cause

Unsupported platforms.

Resolution

Do not accept any error logs from MCE logging tools unless the "—is-cpu-supported" (figure 1.1 part "A.") flag returns a value that matches with a value shown in the list of "Valid CPU’s" (Figure 1.1 part "B.").

The example below does not match and as such, is not a supported platform.
