I have a virtual machine and I have saved a snapshot. It seems that after panic, the file system is damaged, and I cannot successfully repair the file system using journal (SU+J).

Another example is that you are using youtube-dl to download a file, and then the system panic, the file system is damaged and cannot be repaired after restart.

Can SU+J not handle the power outage problem correctly?
