I had a bathroom ceiling that did that. Shock-horror-despair! Also
puzzlement since it was new plasterboard when I first painted it, did
all the right things because bathrooms have a lot to contend with, steam
and splashes. To fix it up after I had peeled off the readily flaking,
peeling paint and rubbed the rest over with sandpaper, I used oil-based
sealer-undercoat with Penetrol and it grabbed like crazy. Penetrol
makes it grab right into the pores of rusty or porous surfaces. EB is
recommended for exterior use, don't know why not interior.

"Take the Flood Adhesion Tape Test: This chalky, dusty surface was
painted with a coat of acrylic paint. An unconditioned paint was used on
the right, while the left was painted with an acrylic mixed with Flood
E-B Emulsa Bond. After the paint had dried, a strip of masking tape was
applied to the surface. The unconditioned paint pulled off with the
tape. With E-B, the tape pulls off, but not the paint."
