Description of problem:
After installing a SNO node with 4.12.54 with Telco DU profile applied and running our cpu utlization tests, the node becomes unresponsive and times out for a very log time (both oc commands and ssh access).
The workload test starts a couple of oslat pods and a number of stress-ng pods for the workload using a portion of the isolated cpus on the BM.
I was only able to collect logs, must-gather, etc. after leaving the node overnight with the workload pods still running . Then oc/ssh commands because responsive again and I was able to collect debugs and logs.
I will attach must-gather, sosreport, etc. in a comment. Please let me know if there are any other logs of interest that I should capture.
Symptoms are similar to OCPBUGS-30096
This issue seems to be specific to systems running with an Ice Lake processor. SPR-EE doesn't seem to have this problem

How reproducible:
Always.
Steps to Reproduce:
1. Install SNO node with Telco DU profile applied.
2. Run RAN QE cpu_util=1h tests
3. Observe test results
Actual results:
test starts workload but then node because unresponsive and times out all commands os the test suite fails.
Expected results:
Test should start workload and run successfully
Additional info:
pod list. Ignore installer pods.
