我这台 Orange Pi AI Pro(Ascend 310B4)存在 NPU 持续告警问题,重启后仍然复现,怀疑是板级供电/LPM/硬件相关异 常,请协助确认。
设备情况: - 板卡:Orange Pi AI Pro 8T - 平台:Ascend 310B4 - 系统:Ubuntu 22.04.3 LTS - 驱动版本:25.2.0 - /var/davinci/driver/version.info 显示: - Version=25.2.0 - Innerversion=V100R001C21SPC008B208
现象: - 执行 npu-smi info 可正常识别设备,但 Health 始终为 Alarm - 系统重启后仍然是 Alarm - 设备支持正常枚举,但无法通过 npu-smi 清除 health,也不支持 reset
npu-smi info 输出: +--------------------------------------------------------------------------------------------------------+ | npu-smi 25.2.0 Version: 25.2.0 | +-------------------------------+-----------------+------------------------------------------------------+ | NPU Name | Health | Power(W) Temp(C) Hugepages-Usage(page) | | Chip Device | Bus-Id | AICore(%) Memory-Usage(MB) | +===============================+=================+======================================================+ | 0 310B4 | Alarm | 0.0 65 15 / 15 | | 0 0 | NA | 0 2136 / 15610 | +===============================+=================+======================================================+

2. /var/log/npu/hisi_logs/device-0/history.log 多次记录: - system exception code [0xA6193215] - ModuleName [LPM] - ExceptionReason [LPM_EXCEPTION]
原始日志: [2026-03-30-01:42:03.733040] system exception code [0xA6193215]: ModuleName [LPM], ExceptionReason [LPM_EXCEPTION], TimeStamp [20260330014200-339902001].

3. /var/log/npu/slog/run/device-os/device-os_20260330014200467.log 反复出现内存 RAS 事件: - drv_memory - error_code: 0x50e
例如: [INFO] ... [ascend] [drv_memory] [event] [mata_ras_event_handler 208] ... [MATA RAS EVENT INFO] sensor_type: 0x0, event_type: 0x3, error_code: 0x50e
已尝试项: - 普通重启:无效,告警仍复现 - 查询 npu-smi clear -h - 仅支持 ecc-info 和 tls-cert-period - 不支持清理 health alarm - 查询 npu-smi set -h - 支持显示有 reset 选项 - 但实际执行时提示:This device does not support setting reset.
固件版本读取正常: - upgrade-tool --device_index -1 --component -1 --version 可以正常读出各组件版本 - 例如 hboot1a/hboot1b/hboot2/ddr/hsm/hlink/atf 等都能正常返回版本号
需要协助确认的问题: 1. 该 LPM Get current error 是否代表板级供电/电流采样硬件异常? 2. Health: Alarm 是否与 drv_memory RAS error_code: 0x50e 直接相关? 3. 该问题是否属于已知 BSP / 固件问题,是否有修复包或升级方法? 4. 如果不是软件问题,是否需要返修或更换硬件?
如果需要,我可以继续提供: - npu-smi info 完整输出 - dmesg 输出 - /var/log/npu/ 下对应日志文件
