1.[FAILED] Failed unmounting /data.日志格式上看起来是systemd配置的unmount流程，fuser查询时/data路径仍被kernel占用；是否复位时序上没有处理好，或是内核打开了某个句柄一直未关闭

2.[ 703.632639] xhci-hcd xhci-hcd.1.auto: Host halt failed, -110驱动报错，RTOS同事表示未交付过XHCI这个ko，BMC是如何使用到这个驱动的呢

【问题求助】BMC串口日志中出现异常日志，该如何分析是否为问题

  1. 已知问题，之前已分析解决了其他分区的卸载的失败问题。复位过程先停止了所有的用户服务和进程，再卸载的分区，复位时序上是正常的，初步怀疑跟内核有关，待进一步分析确认，当前评估影响低。
