This problem simply doesn't make sense.  There's just no way we shoud be
able to get a not-uptodate folio into the page tables.  We do have one
pending patch which fixes a situation in which we can get some very
odd-looking situations due to reusing a page which has been freed.
I appreciate your ability to reproduce this is likely nil, but if you
could add

https://lore.kernel.org/all/20231220214715.912B4C433CA@smtp.kernel.org/

to your kernel, it might make things more stable for you.
