I've not been able to reproduce this locally yet, but I'm looking into it. In the meantime, a few questions if you have time: - Does this happen with CONFIG_KUNIT=3Dy as well as CONFIG_KUNIT=3Dm? - Does this patch fix it? https://lore.kernel.org/linux-kselftest/20230225014529.2259752-1-davidgow@g= oogle.com/T/#u I can't think of any particular reason this commit would cause these problems, but there were some issues with the way these 'hooks' were built, so it's possibly related. Sorry again for the inconvenience!
