Good day,
I wanted to upgrade my kernel to the latest 5.15.162 but it seems to fail with this error message after upgrading to fedora 40, any ideas what could be the problem?

Maybe a problem with gcc 14?
Maybe, has any previous 5.15.y kernel worked?
My current kernel was compiled with gcc 13: [ 0.000000] [ T0] Linux version 5.15.160 (thomas2@localhost.localdomain) (gcc (GCC) 13.3.1 20240522 (Red Hat 13.3.1-1), GNU ld version 2.40-14.fc39) #15 PREEMPT Sat Jun 1 16:54:27 CEST 2024
If you build 5.15.160 with gcc 14 does it also fail? Doing a 'git bisect if it does not would be great to track down the offending commit.
thanks,
