Whatever is loose has to come off. Covering it with "something" will just
result in the "whatever it is" to peel off with a coat of the new
"something" you put on it.

Could it be old wallpaper underneath? Does it have like air bubbles?
In a case where it is wallpaper, what happens is the room moisture gets
through the latex paint and causes the old wallpaper to bubble and maybe
"flake". If you think this might be the case then:
- Scrape, gouge, cut with util knife, etc all the loose stuff until you
have all solid areas.
- Prime entire wall with oil based primer. Let it dry WELL. "Kills
Oderless" works. Don't use the Kills that is not oderless that is a buck
or two cheaper. It stinks HORRIBLY BAD. Get the primer tinted 3/4 of the
final color. Paint store/dept should have a machine setting to tint to
3/4 of the color you give them.
(If it is wallpaper under there somepalce, if you put latex primer or
paint and/or mud on it, places that were not messed up will start to
bubble.)
- mud and smooth out
- prime again with latex or oil based primer. Might as well use oil since
you already have some and a roller loaded up with it. After the first
priming, wrap the roller cover in plastic wrap so it doesn't dry.
- paint with latex paint
