Shutdown failure log:
Kernel BUG at fs/jfs/super.c:119
We can see from the preceding figure that the system attempted to delete a device that was already mounted when it was shutting down. However, the device was being accessed at the time, as a result, the device failed to be deleted, and therefore the shutdown failed. The symptom was that the power-off process halted. This was due to a Linux kernel bug.
