Thanks for picking this up and moving it forward. I've reviewed patches 1 - 3, and took a quick look at 4 - 7 (which also look fine at a glance). -Frank > > Thanks, > Andrew > > Changes from v1[1]: > - Added patch to rename pi433 overlay. > - Cleaned

The patch commit 941214a512d8c80d47e720c17ec17e8539175e93 Author: Andrew Davis <afd@ti.com> Date: Mon Oct 24 12:34:29 2022 -0500 kbuild: Allow DTB overlays to built into .dtbo.S files broke the build reproducibility / no-op builds. Before: 2+ execution of `make` on non-changed tree did nothing Now: Each run of `make` (even without a single bit changed) restarts vmlinux rebuild. Please, revert or fix.

For your reference I started with this one [1]. When I bisected, I just answered with defaults on whatever `make` told me at the configuration stage. The actual `make` command I used: make O=/path/to/the/result W=1 C=1 CF=-D__CHECK_ENDIAN__ -j64 But there is nothing that can affect the described issue.

Just to confirm, I reverted the patch and everything went fine again, so simple revert helps! (Tested on today's Linux Next)

As far as I can tell right now it's the OF_UNITTEST on x86_64 that makes the above mentioned patch to be a culprit. Not sure if on ARM / ARM64 you can reproduce that.
