    I have installed Linux on a Sata drive in a HP ML310e Gen8 server box recently acquired.

    There is a single HDDs and is set to use the embedded SATA controller rather than the RAID controller.

    DMESG has the following message repeated regularly .... not sure how often, but a few every minute it seems ......
    ACPI Error: SMBus/IPMI/GenericSerialBus write requires Buffer of length 66, found length 32 (20120320/exfield-299)
ACPI Error: Method parse/execution failed [\_SB_.PMI0._PMM] (Node ffff880106254118), AE_AML_BUFFER_LIMIT (20120320/psparse-536)
ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMM (20120320/power_meter-348)

    Have you any idea of the cause of this error?

    Thanks for reading ;)

    Not much help, but the error comes from this file: https://github.com/torvalds/linux/blob/507a03c1cba0e32309223d23d19a1bfc0916c140/drivers/acpi/acpica/exfield.c

    According to Novell/SuSE enterprise help forum:
    It is just a warning. The messages are occuring since a script or an application is reading from certain kernel ACPI parts under /sys/devices/LNXSYSTEM:00/ which are not fully implemented yet.

    For SLES11 SP2 the issue is fixed since kernel version 3.0.26-0.7.6.

    So upgrade required already, or you can safely ignore...

    Thanks, I am running a newer kernel ... have to check but think it is 3.4.66 or close.

    The damned messages are cluttering up the dmesg output even if they are not important :(

    My understanding was that a warning would say 'Warning' and error 'Error' ...... BTW, not using Suse but I guess that hardly makes any difference.

    Installed a 3.10.7 kernel and the messages have disappeared!

    Thank you for the solution ;)
