We have seen great work (fixes) for gcc-12 when it got released. I think I / We should not expect this with gcc-13 since it takes more work. As I understand, stable-rc 6.1 testing with gcc-13 would be ok. other than stable-rc 6.1 branches 5.x and 4.x should be built with gcc-12. > > So when you run into issues like this, that obviously work in newer > kernel releases, a report doesn't do much, BUT a git commit id of what > the commit that needs to be backported IS appreciated. Thanks for explaining the details here. If I come across any fixed patch / commit id then I will share that information. > > thanks, > > greg k-h thanks, Naresh Kamboju
