CentOS - Feb 2019 - Centos bug 15570 - Not just a VBOX bug, can also reproduce on direct hardware install

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-3.10.0-957.1.3.bug15570.plus.el7.x86_64.rpm
wget
https://people.centos.org/toracat/kernel/7/plus/bug15570new/kernel-devel-3.10.0-957.1.3.bug15570.plus.el7.x86_64.rpm

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.

As noted in the CentOS bug report you referenced (
https://bugs.centos.org/view.php?id=15570 ), I filed a report upstream
( https://bugzilla.redhat.com/show_bug.cgi?id=1658669, marked
private). In that RHBZ, they were able to reproduce it without
VirtualBox. Therefore they are aware this is not just a VBox problem.
The fix has been added to kernel-3.10.0-984.el7, meaning it will be in
the EL 7.7 kernel.

Now there is a separate RHBZ for "Z-Stream" for the same issue. This
means that the fix will be ported to the current series (EL 7.6).
Unfortunately I have no access to this BZ, so cannot tell the progress
there. Once it is fixed in RHEL, CentOS will inherit it.

I added the following note to bug 15570:

"The problem is not unique to VirtualBox. It can be reproduced _without_
VBox."
