Hi,
I got this installed in a Vbox VM on Windows10 host this evening. I was able to trigger this issue after a third reboot after the update to 7.5.
This is a kernel OOPS and this distro does a default panic_on_oops ... so what I did to get the full stack is to set:
kernel.panic_on_oops = 0
in
/etc/sysctl.d/tpe.conf
The system still fully boots if it runs into this issue, and you can find the relivant info in /var/log/messages - the stack trace is here:

That's all the time I have for tonight - I'll continue taking a look at what's causing this over the next few days.
Thanks for the report.

I am wondering if the problem has gone away with another kernel update to kernel-3.10.0-862.9.1.v7.x86_64. I have not been using my VM too much but it has not crashed since the update at the end of July. Today the kernel went up to 3.10.0-862.11.6.
