    It is only the Dell Latitude E6410 affected?

    Mario, do you have any information about that API from Dell?

    They are included in following files:
    /sys/class/dmi/id/sys_vendor
    /sys/class/dmi/id/product_name

    Beware that they may contain whitespace characters and it is important.

    I would usually suggest to run dmidecode and attach an output somewhere.

    (Just my 2 cents :-) )

    Pali,

    I believe this particular API shouldn't have changed over generations, so it's
    likely something that needs to be quirked for that generation.
    I haven't had a chance to check on this yet in detail though.
    For now could you guys quirk this one and if I find out there was something more systemic we can undo the quirk and do something more broad.

    Thanks,

    Ok! Gabriel, can you provide us your DMI information about your machine?
