I tried to find the problem, but I still think that their SD card is broken. It is not true. It's just that Linus himself spoils files when the power is removed abruptly! Therefore, you can get bus error and similar scary messages

The topic is no longer new, but I have not found the reason and its solution!
 
If you turn off the power (just pull out the wire) then you can get a non-working system. 
As I noticed, the files opened at the time of launch are broken. And some files such as /etc/boot/armbianEnv.txt in general, they are recorded with some kind of garbage!!!
 
Because of this, your settings fly off! For example, I use ttys1 and this option is registered armbianEnv.txt , but after the power loss, there is just terrible garbage in this file, as if the memory dump fell there!!! For example, I still use dotnet, so it also breaks down and does not start anymore!! When you try to run dotnet from the command line, you get a bus error! Of course, deleting and reinstalling it solves the problem. You may also get problems with apt!
 
I certainly expected this from windows. But for linux to be somewhat unreliable is a tin and a disappointment!!
Why does this happen and how to treat it???
 
Now I have made a sh script to check the integrity of files and restore them. But these are crutches and a shame for linux!!! Maybe arabian is crooked and unreliable? 
or is it a disease of all systems???
I must say right away that the SD card is normal! This has been tested on 10 minicomputers. It's the same problem everywhere!
