Not sure this is the actual cause
Comment 1 Randy MacLeod 2023-12-07 15:40:05 UTC 
Randy will discuss with co-worker and either get the issue fixed or skip the test or all mdadm ptests even.

Comment 5 Randy MacLeod 2023-12-21 20:09:42 UTC 
Add Ovidiu so he knows what's going on.
Pavel is going to disable all the mdadm ptests and try to work to get some of the many patches merged upstream.

Comment 9 Pavel Zhukov 2024-01-24 21:47:31 UTC 
This bug "fixed" by disabling ptests for mdadm [1]
Once upstream makes new release we may want to revisit this decisions and re-enable the tests together with cleaning up downstream patches.
