Devel:Kernel:master/kernel-source:kernel-vanilla/LEGACYX86/i586 build log

The kernel builds result in random build failures while creating BTF.

For example
https://build.opensuse.org/package/live_build_log/Kernel:vanilla/kernel-source-vanilla:kernel-vanilla/ARM/armv7l:
> libbpf: failed to find '.BTF' ELF section in vmlinux
> FAILED: load BTF from vmlinux: No data available
> make[2]: *** [../scripts/Makefile.vmlinux:34: vmlinux] Error 255
> make[2]: *** Deleting file 'vmlinux'
> make[1]: *** [/home/abuild/rpmbuild/BUILD/kernel-vanilla-6.11~rc3.338.gc3f2d783a459/linux-6.11-rc3-338-gc3f2d783a459/Makefile:1158: vmlinux] Error 2
> make: *** [../Makefile:224: __sub-make] Error 2
> error: Bad exit status from /var/tmp/rpm-tmp.olf5Nu (%build)

arm seems to fail reliably.

But for example in
ibs://Devel:Kernel:master/kernel-source:kernel-vanilla/LEGACYX86/i586, it looks
like it is sort of random. kernel-debug and kernel-vanilla fails for i586, but
-default and -pae are built currently. See the job history for kernel-vanilla
in there (the failed boot log is attached):
