Hello, @VV0001​:

Thank you for contacting Intel Embedded Community.

Could you please let us know how many units of the project related to this circumstance have been manufactured? How many are affected? Could you please give the failure rate?

Could you please provide topside markings pictures of the processors associated with this issue?

We are waiting for your answer.

Best regards,

Hi Team,

Thanks for your kind response. Please find our answers in line below.

How many are affected? one unit is affected.

Could you please provide topside markings pictures of the processors associated with this issue? We have requested with the concerned team, will provide you this at the earliest.

In addition to our above questions, we have few more queries below.

1. What does MCE error (kernel panic) mean?
2. Whether the MCE log decoding mechanism used by us are correct or not??
3. Whether above MCE log decodes to error: Generic Cache level-2 Generic error and also Processor context corrupt for Bank 17 and Bank 19??
4. Let us know what is the cause of MCE from the decoded MCE log. Whether is it a Hardware failure (CPU internal itself) or Software failure which handling some function??
5. What does it mean by Generic CACHE Level-2? Whether Cache memory Internal to the CPU?

Please let us know from the above decoded MCE log whether in future it will affect health of the board as node seems to be working fine now.
