ACPI Error: SMBus or IPMI write requires Buffer of length 66, found length 32

 

There are numerous bug reports about errors like this appearing on HP servers running various Linux distributions

The error is

   ACPI Error: SMBus or IPMI write requires Buffer of length 66, found length 32

I've observed it on a MicroServer Gen8

 

These two bug reports suggest a BIOS update is required to fix the issue:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1079544

https://www.novell.com/support/kb/doc.php?id=7010449

but I already have the latest BIOS, version J06

Will HP release another BIOS update for the MicroServer Gen8 with this fix?

I'm getting the same error on Centos 7 with Proliant Microserver Gen 8:

Oct 31 10:47:30 srv kernel: ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM (20130517/power_meter-339)

Bios Version:

dmesg |grep -i buffer\ leng 

 

 

return nothing.,so is ok.
