The following page fault was observed during the exit moment of the HIP test process. In this particular error case, the HIP test (./MemcpyPerformance -h) does not require the AQL queue. As a result, the process_context_addr was not assigned when the KFD process was released, ultimately leading to this page fault during the execution of kfd_process_dequeue_from_all_devices().
