Here is the update on this bug. Four use cases:

[1] With kernel 4.8.1-1.fc25.i686, this bug is present when number of virtual CPUs is 1.
[2] With kernel 4.8.1-1.fc25.i686, this bug is NOT present when number of virtual CPUs are 4.
[3] With kernel 4.8.2-300.fc25.i686, this bug is NOT present when number of virtual CPUs is 1.
[4] With kernel 4.8.2-300.fc25.i686, this bug is NOT present when number of virtual CPUs are 4.

This issue is (magically) solved. I need the following:
(1) Root Cause of the problem (what was wrong with use case [1])?
(2) Solution for (1)!

Thank you!

To be perfectly honest, nobody is going to look at this bug.  The combination of multiple virtualization technologies that are not KVM combined with a 32-bit kernel means this is literally the lowest bug on the priority list.

We appreciate the report, but we wanted to set expectations accordingly.  We are glad you have found a workaround.

Hello Josh (Boyer),

I do agree on what you have wrote here. I also declare Case Closed.

But in this regards, I wrote the new bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1387361

Good luck on this one (you'll need it)! ;-)
