I keep getting this constant error:

Feb 22 23:00:56 Tower kernel: ACPI Error: SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32 (20170728/exfield-427)
Feb 22 23:00:56 Tower kernel: ACPI Error: Method parse/execution failed \_SB.PMI0._PMM, AE_AML_BUFFER_LIMIT (20170728/psparse-550)
Feb 22 23:00:56 Tower kernel: ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM (20170728/power_meter-338)

 

I read that I should add this to the end of the /etc/sensors3.conf file but its still happening. It started in 6.4 and I updated to 6.4.1 hoping it would fix the issue.

chip "power_meter-acpi-0" I also tried chip "power_meter-*" 
        ignore power1

Nevermind I figured it out. The power-meter was added to the kernel but my system never had an issue before. The solution is modprobe  -r acpi_power_meter

 

See here, and Tom's response immediately below.

Thanks, I will add the fix.

Well I tried the method listed in the post you linked and yes it ignores the sensor reading but I am still getting the error.

What hardware are you using? Mine is a HP Microserver Gen8 and the fix worked for me and I know that other HP Proliant owners are using it. Is the sensors-quirk file being copied properly by the go file when you boot? You can test by manually copying it from the boot flash to the /etc/sensors.d folder.
