Unfortunately, when I tried to mount the image with a loop devic= e, the kernel deadlocked. I have attempted many ways to stop the mount process, even executed a 'kill' command, but they are failed, only what I can do is = to reboot the system. Can anyone tell me why the kernel deadlocked, and how ca= n I fix this problem? I have upload the image to the Google Drive (https://drive.google.com/file/d/1NjUKdMufpoiyMscpFMdbiwOzyOios-aa/view?usp= =3Dsharing).
