Bug report
Bug description:
We have recently started to see the following test failure on Fedora CI with Python 3.14.0rc3 and 3.13.7 (possibly others as well, not tested yet):
This is similar to #73510 and seems to have regressed again. Not sure if this is a kernel bug or CPython bug yet.
CPython versions tested on:
3.14, 3.13
Operating systems tested on:
Linux
