## Observation 

 openQA test in scenario sle-12-SP3-Server-DVD-aarch64-RAID0@aarch64_raid fails in 
 [partitioning_raid](https://openqa.suse.de/tests/900626/modules/partitioning_raid/steps/132) 

 The test fails selecting the disks for raid 

 ``` 
 I found one issue on aarch64 in setraidlevel() from partitioning_raid test. But most probably it is a general problem of aarch64, the same test is passing on x86_64 without problem. 

 When selecting wanted RAID level some keystrokes (eg. alt-i, Tab) are ignored and then the test is failing, see https://openqa.suse.de/tests/903726#step/partitioning_raid/132 

 The problem occurs on all aarch64 worker but time to time seattle6 can pass the test. I newer saw any other aarch64 worker to pass the test before. 

 I already changed test code to using wait_screen_change {send_key ... } but it didn't help https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/2777 

 Could be that virtio-gpu-pci generates some noise in video output? Otherwise I have no idea. 

 After solving this we should remove WORKER_CLASS=aarch64_raid from o.s.d settings.

 ## Reproducible 

 Fails since Build [0348](https://openqa.suse.de/tests/900626) (current job) 
 First time that happens. 


 ## Expected result 

 Last good: [0347](https://openqa.suse.de/tests/898705) (or more recent) 


 ## Problem 
 * **H1** The product has changed 
  * **H1.1** product changed slightly but in an acceptable way without the need for communication with DEV+RM --> adapt test 
  * **H1.2** product changed slightly but in an acceptable way found after feedback from RM --> adapt test 
  * **H1.3** product changed significantly --> after approval by RM adapt test 

 * **H2** Fails because of changes in test setup 
  * **H2.1** Our test hardware equipment behaves different 
  * **H2.2** The network behaves different 

 * **H3** Fails because of changes in test infrastructure software, e.g. os-autoinst, openQA 
 * **H4** Fails because of changes in test management configuration, e.g. openQA database settings 
 * **H5** Fails because of changes in the test software itself (the test plan in source code as well as needles) 
 * **H6** Sporadic issue, i.e. the root problem is already hidden in the system for a long time but does not show symptoms every time 


 ## Further details
