Hi,

were you able to reproduce this problem? I tried it, but it worked everytime. It passed in these version:
  * tuned-profiles-cpu-partitioning-2.7.1-5.el7fdp.noarch (rhel-7.3 fdp)
  * tuned-profiles-cpu-partitioning-2.8.0-5.el7.noarch (rhel-7.4)
  * tuned-profiles-cpu-partitioning-2.8.0-5.el7_4.2.noarch (rhel-7.5)

Do you know where is the problem? How to reproduce this bug?
