Comment 1 wangsy30 2017-02-14 03:59:17 EST

Upstream has fixed this issue:

commit 12fbde92a26da61eda9f2ff0ba3c316779163f10
Author: Jean Delvare <jdelvare@suse.de>
Date:   Fri Jan 20 10:57:12 2017 +0100

    Only decode one DMI table

    Since version 3.0.0 of the SMBIOS specification, there can be
    multiple entry points in memory, pointing to one or two DMI tables.
    If both a 32-bit ("_SM_") entry point and a 64-bit ("_SM3_") entry
    point are present, the specification requires that the latter points
    to a table which is a super-set of the table pointed to by the
    former. Therefore it makes no sense to decode both.

    Per specification, look for a 64-bit ("_SM3_") entry point first, and
    if we can't find any, look for a 32-bit ("_SM_" or "_DMI_") entry
    point.

    This fixes bug #50022:

dmidecode.spec

I uploaded 2 patches and dmidecode.spec. Test is passed on board which has SMBIOS 3.0.

Petr Oros,
According CHANGELOG, it seems there is no update after 2015-11-02 , 
I advise add all upstream patches besides the 2 patches I attached.

Comment 7 Petr Oros 2017-02-15 04:42:49 EST

Hi,
I agree with you. Will do.

Thanks,
-Petr

Comment 10 Mike Gahagan 2017-05-03 15:46:06 EDT

The SMBIOS 3 based system I have access to doesn't seem to reproduce the bug however I can confirm the fix is in dmidecode-3.0-4.el7.
