This is very odd, as there seem to be not ntfs3 related changes in the
changes between v6.12.32 and v6.12.33 (which was as well a very small
release).

A couple of things:

1. Can you please try as well 6.15.4-1~exp1 in experimental to verify if
   you can trigger the issue there as well?

2. Can you please still do the following, but each kernel respective,
   mount the NTFS volume and try to write to it. Then paste the full
   dmesg you get for both 6.12.32-1 booted system and 6.12.33-1
   bootest system.

3. If you feel confident, can you bisect the changes between 6.12.32 and
   6.12.33 to pinpoint the commit which "breaks" so we might hopefully
   be able to narrow down more closely the problem?

Regards,
Salvatore
