Thanks for reporting. Can this issue be reproduced with the latest mainline linux kernel? Can it work if you simply revert this commit?

Thanks, baolu

Hi, baolu

The issue cannot be reproduced on the latest mainline kernel (6.16.0-rc7-1-mainline). The Ubuntu v6.14-series kernel which also include the commit is also not affected. I think the issue only affects the v6.12 series in linux-stable tree. Should I wait for the stable maintainers to solve it?

Nope! We need your help as you are the one that can reproduce it :)

Are we missing a backport? Did we get the backport incorrect? Should we just revert it?

thanks,
