This looks like something that happens at boot / hardware setup time and not while the system is running "production". Thanks for the feedback. > Any idea/suggestion is definitely appreciated I've been interested in cases which can stack up beyond 2 and can be triggered by users because these may influence the RT workload. The pm-case has been filtered out because nobody should do RT a workload while PM is going up and down. The report I got was in the init-phase of crypto which does not trigger usually and shouldn't trigger at run-time once everything is set up. Feel free to raise the bar here to avoid the warning in your case here. I'm currently thinking about removing the warning due to lack of new cases. > Best Regards, > Marouen. Sebastian
