[SOLVED] Compiling 6.3 kernel fails (testing)

Hello. I spent the day trying to compile kernel 6.3, but without any luck.

In the it always ends up failing like the following:

  CC [M]  drivers/infiniband/hw/hfi1/vnic_sdma.o
  CC [M]  drivers/infiniband/hw/hfi1/debugfs.o
  LD [M]  drivers/infiniband/hw/hfi1/hfi1.o

    Aborting...

Using the following: PKGBUILD.
What am I missing, is the upstream not ready for building yet?

Building from 6.2.13.
All packages up-to-date.

Re: [SOLVED] Compiling 6.3 kernel fails (testing)

What if you build it in a clean chroot using  `testing-x86_64-build` so pahole 1:1.25-3 from testing is used?

Wow that really did the trick.
Thank you so much, I totally forgot that there may be other updates in testing that could fix this. <3

Re: [SOLVED] Compiling 6.3 kernel fails (testing)

Are any other packages required?

I installed kmod, mkinitcpio, and pahole 1.25-4 for my chroot, and still received the above error.
