SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32

today my nas debian 9 based started to write out this error in the startup phase, the same is reported in red by calling journalctl -xe: ACPI Error: SMBus/IPMI/Generic write requires Buffer of length 66, found length 32 (20160831/exfield-427) ACPI Error: Method parse/execution failed [\SB.PMIO._PMM] (Node ffff8a71878aeaf0), AE_AML_BUFFER_LIMIT (20160831/psparse-543) ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM (20160831/power_meter-338) I have a double raid1 (**sda/sdb** and **sdc/sdd**) inside this nas, could it be that one of the disk is going to be defective ? Should I be worried ? What could have caused this error and how can I fix it? Could it be an error given by the fact that I pressed the power off sometimes instead of login and write manually shutdown -h now ? Thanks
