The device is there, right? > So fix Linux drivers if they cannot handle it properly. CoreSight devices build a path from source to sink and defer probing if any device in the path is unavailable so the deferred‑probe behavior is expected. We could add logic to fix it in driver but it's much easier to address it in DT because we are knowing the device is disabled/Failed in DT. It's my fault I didnt remove this disabled replicator device in previous fix. Thanks, Jie > > Best regards, > Krzysztof
