Unable to Run GNOME or KDE due to "dmidecode" segmentation fault

[rrs64]

Hi All:

I've installed the following CentOS 7 image onto an SD card which successfully boots the RockPro64 with 4 Gb RAM and eMMC card:

    Centos-7.4.1708 with kernel from Armbian-5.67.img.xz

It was downloaded directly from the Project31 GitHub web page:

    https://project31.github.io/pine64/

After first boot the /root/finish-centos-install.sh script was run to complete setup.

Then GNOME was installed with the following command which completes successfully:
    

Code:

# yum -y groups install "GNOME Desktop"

Next, attempt to launch GNOME using the command:

Code:

# startx

It fails to launch due to a segmentation fault from "dmidecode" shown below:

The same segmentation fault occurs at the command line if "dmidecode" is run by itself.

Re-booting, 'yum update'. or starting over with a new SD card does not help.

Has anyone else had the same problem trying to install and run GNOME (or KDE) on CentOS on RockPro64?

This issue is a real blocker trying to get a graphical interface up and running.

Any hints or suggestions are welcome.

Thanks
