Hi Yunjian, That's interesting. Is it possible to elaborate the use case or possibly provide the code snippet? It is possible that it is a synchronization problem due to relaxed memory model that Arm architecture uses. There could be a barrier missing in the code.

However, the x86 platform does not have this problem. Any ideas ? Thanks, Yunjian
