I propose following:
Install and test with latest centosplus kernel (I use them exclusively
because all drivers are enabled and some stuff is added/enabled that
RHEL disables for speed since they do not not need them).

After you test centosplus kernel, not matter the outcome, file a bug
report with all the details at https://bugs.centos.org so devs can
triage the problem.
