    Default ACPI Errors when booting on 4.9 Kernel

    Since I am on 4,9. I have been getting these errors when I boot. They seem harmless, but I would kust like to make sure:

    After looking at the logs, it appears I have been getting this error for a while, they were just not displayed.

    Hi
    Is the system BIOS up to date? Similar to this (closed won't fix) bug;

    Hi
    What type of DELL system? It's the acpi DSDT table, if everything is working (Fn keys for vol, wifi, brightness, lid switch etc), you should be fine... You could perhaps look at raising a kernel bug, but think they will advise to talk to the DELL folks...

    FWIW, I have a DELL Inspiron 5555 with A12 firmware rev 65.12 and don't see any acpi errors.

    All the function keys etc. seem to be working. So should I suppress those events in the log?

    those events in the log?


    Hi
    Perhaps you could as long as everything is working as expected, just
    keep an eye out for a BIOS update, if it starts playing up with later
    kernels you might need to re-enable...

    This is the relevant section of dmesg with a Acer Aspire V

    Code:

    It also appeared with the arrival of the 4.9 kernel.

    I've got no idea if there is a real problem or not (so, "not", then...) but it's not only Dell.

    I get similiar entries since up-dating to 4.9.

    Default AW: ACPI Errors when booting on 4.9 Kernel

    After looking at the logs, it appears I have been getting this error for a while, they were just not displayed.
    Exactly, so the ACPI errors have always been there, 4.9 just seems to do a "better"(?) job in displaying them on startup.

    Such warnings/errors are pretty common and as long as you don't experience any serious problems, just ignore them.

    Although being a standard, ACPI is the one often being ignored (on purpose?) by some (many, most?) vendors, just think of those funny kernel paramters sometimes needed to "trick" the BIOS so it "thinks" you are running some Windows OS in order to get access to functions otherwise being blocked.

    As GKH once said "ACPI code is nasty".
