When tuned pod gets restarted tuning gets reapplied even though no configuration changes are required. I have found that in a scenario where we have a testpmd application with traffic running, restarting tuned pod may lead to the SNO node locking due to RCU stalls. Ideally tuning should not get reapplied on restart when there are no config changes.  

4.14.0-rc.7

100%

1. On an SNO with DU profile applied restart tuned pod
2. Check tuned logs
