Ran into this rather frustrating bug when working with VBOX on a Windows 10 host. It should come as no surprise that I would hit this bug when installing CentOS, and also with RHEL 7 Server with GUI (since you get the same kernel). Based on information from your bug list, I was fortunately able to workaround the trouble with:
wget https://people.centos.org/toracat/kernel/7/plus/bug15570new/kernel-3.10.0-95... wget https://people.centos.org/toracat/kernel/7/plus/bug15570new/kernel-devel-3.1...
yum -y localinstall kernel-3.10.0-957.1.3.bug15570.plus.el7.x86_64.rpm yum -y localinstall kernel-devel-3.10.0-957.1.3.bug15570.plus.el7.x86_64.rpm
However, the bug lists seem to refer only to issues with VirtualBox. I have experienced the same symptom when installing on a "hardware" system (no hypervisor). The same commands above also provide a workaround here, but thought the flag should be raised for CentOS and RHEL that it doesn't seem to be just VBOX.
Perhaps the priority of this issue should be raised further up the pole since I can't imagine it being a good experience for someone who doesn't know how to dig through a problem like this. The average bear would install something else and move on.
In any case, thank you for the patch information. Look forward to a "real" fix soon. Other than that I'm really liking CentOS 7.
