<![CDATA[ACPI Error: SMBus/IPMI/GenericSerialBus]]>With the latest XCP-ng updates, I am getting dmesg errors. They appeared immediately after yum update finished, and remain after reboot. Anyone seen this before and knows what to do?

This is a HPE DL325 Gen10 EPYC system with XCP-ng 8.2.1.

I stopped Netdata and the problem went away. But it is strange it started after the latest set of updates.

Would that have any impact in XCP-ng - i.e. is this feature used by anything?

EDIT: Perhaps it is netdata. I will disable netdata and check again.
