A hotfix RT kernel is available that fixes this issue:

Comment 12 Pei Zhang 2019-04-17 13:42:40 UTC

Verified with kernel-rt-3.10.0-957.12.1.rt56.927.el7.x86_64.

Scenarios: 
- The three standard KVM-RT testing scenarios with 24 hour cyclictest - PASS
- Boot/Reboot/Shutdown works well - PASS

Move to 'VERIFIED'.
