However, the internal abort timed out due to the 2 bit ECC error and triggers automatic dump. In addition, since the hisi_hba semaphore has been obtained, the dump cannot be executed and the controller cannot be reset. Therefore, the deadlocks occur on the following circular dependencies ---truncated---
