Are you disabling debug flags?
Our build with thinlto went through so far.
I see, the CI is also failing:
https://github.com/CachyOS/linux-cachyos/actions/runs/8024032122/job/21921711315
We need to look into. You maybe need a kernel, which already has the latest bpf changes from archlinux
I would suggest you to maybe revert the changes, or compile the kernel in a chroot:
Here a example of the revert (cause hardened does not provide bpf support):
4642e6b

The revert worked. Build is successful. No need to chroot on my machine since I have multiple custom kernels installed.
I compiled the kernel with this setting and it worked fine. We need to take a look at this

From my further testing, the error only occurs when _disable_debug flag is enabled. The build is successful without the revert and the flag is not set.
