 openQA test in scenario opensuse-Tumbleweed-NET-ppc64le-minimalx@ppc64le fails in 
 [yast2_lan](https://openqa.opensuse.org/tests/801707/modules/yast2_lan/steps/1) 
 yast2_lan because of rcu message in root-console (ppc64le) 

 extract of serial0.txt 
 ```

 ## Observation 

 openQA test in scenario opensuse-Tumbleweed-NET-ppc64le-minimalx@ppc64le fails in 
 [yast2_lan](https://openqa.opensuse.org/tests/801707/modules/yast2_lan/steps/1) 


 ## Reproducible 

 Seldomly Fails since (at least) Build [20181120](https://openqa.opensuse.org/tests/801707) (current job) 


 ## Expected result 

 Last good: [20181118](https://openqa.opensuse.org/tests/800828) (or more recent) 

 ## Suggestions 

 * Investigate what the message means 
 * Look into preventing that message in tests or reference product issue with soft-fail and workaround (needle is already in place but references this "test issue" ticket instead) 


 ## Further details 

 Always latest result in this scenario: [latest](https://openqa.opensuse.org/tests/latest?machine=ppc64le&test=minimalx&distri=opensuse&version=Tumbleweed&arch=ppc64le&flavor=NET)
