    Question MCE decoder support:

    Hi all
    And thanks in advance.

    I'm wondering if anyone else has ever seen this kind of thing;
    { Posted in console log (CTRL+ALT+F10) and on screen popup
    Message from syslogd@linux-114 at Jun 20 14:12:57 ...
    kernel:[ 6757.000089] [Hardware Error]: Run the message through 'mcelog --ascii' to decode.
    }
    { Posted to (/var/log/messages)
    Jun 20 14:17:57 linux-114 kernel: [ 7057.000044] [Hardware Error]: No human readable MCE decoding
    support on this CPU type.
    Jun 20 14:17:57 linux-114 kernel: [ 7057.000079] [Hardware Error]: Run the message through 'mcelog
    --ascii' to decode.
    }
    I know the time stamps are not the same but I get this message quite a bit.
    It seem to be harmless, but it is a real nusense when I'm trying to record an audio file.
    BTW How do I turn off this alarm?

    Thanks J.B.G.

    MCE stands for Machine Check Error, which is linux gobbledygook for a
    hardware error. The kernel is telling you that it's detected faulty
    hardware in your machine. Do what it says and run it through mcelog to
    find out what the problem is.

    Then fix your hardware and the messages will go away.

    Most users do not have the wherewithal to fix BIOS code and are reliant on system vendors.
    I'm at this page because I'm stuck with an HP DL580G7, which spams these periodically:

    [Hardware Error]: Machine check events logged

    Message from syslogd@eng0-linux at Jul 22 23:05:34 ...
    kernel:[Hardware Error]: No human readable MCE decoding support on this CPU type.

    Message from syslogd@eng0-linux at Jul 22 23:05:34 ...
    kernel:[Hardware Error]: Run the message through 'mcelog --ascii' to decode.


    HP appears to indicate that a future BIOS update will address this.
