Ok, so that's not enough, must be something else.
I guess you are right next step should be analysis of the image.
zImage however can hardly be used for that.

Erhard, were you able to redo the test with DISABLE_LATENT_ENTROPY_PLUGIN also
disabled for early_32.o ?
If you can try with it disabled for both early_32.o and setup_32.o

early_32.o should likely also have DISABLE_LATENT_ENTROPY_PLUGIN, maybe even

POWER9 doesn't have KASAN.
Did you try G4 without KASAN ?
