Hello!
Moved into a 40s house with a basement. Now parts of the rough wall are coming off all the way down to the foundation concrete. As you can see, there are 3 layers coming off: some filler, some fine filler, and paint. Efflorescence can be seen here and there, and therefore it's the moisture migration causing the problem.
What would you do? Is it just a matter of knocking off these layers and redoing it properly? Or should I just patch up where these large holes appear?

I would recommend following the principle of removing too much rather than too little. If it's firmly in place, it can remain. The motivation for the extra work is the reduced risk of having to redo the job. But a more important question in this context, have you addressed the cause of it coming loose, i.e., reduced the moisture load?
Thanks for the input!
Yes, measures for moisture movement as far as I can are addressed!
