I use Virtual Environment 5.4-13
My problem is with a guest machine with CloudLinux.

My server crashed and when I opened the console it appeared:

After resetting the system, I encountered this and it froze:

Reset did not solve the problem:

Finally, when booting, I changed the kernel version from 7.9 to 7.7 (the second option in the image below) and the system came up well:

Some C-Panel warnings that I'm not sure are relevant: (just because I saw root in errors)

Of course, the error messages are many and confusing, but for example, for this error: "Kernel panic not syncing VFS unable to mount root fs on unknown-block" that I searched, they said I should use "update-initramfs". But I'm not sure.

Where do these problems come from? What is your advice now? What do I need to do? How do I get back to my default 7.9 kernel state without seeing these errors?

Thanks
