Apologies in advance, but I cannot git bisect this since machine was

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
to your kernel, it might make things more stable for you.
Ok looks like that's in mainline - machine is now running 6.7.0-rc7 - unless you prefer I patch 6.6.8 with above and change to that.
thanks and sorry about bringing up wacky problem.
