Another strange symptom is that the problem did not happen when

What happens with the not-even-compile-tested debug patch below?
Now I have the results of that test. It does not trigger at all during
normal shutdown since module is not unloaded. When I unmount openpromfs
and rmmod openpromfs, both lines are promted to dmesg. After that, the
RED state still happens on reboot.
Ok, thanks for testing that.
The slab debugging seems a promising line of inquiry.
