linux_next - I did allmodconfig build prior to running the tests.
That means I had to run make ARCH=x86_64 mrproper before running

./tools/testing/kunit/kunit.py run --arch x86_64

I tried something different checking out a fresh
linux_next repo and running ./tools/testing/kunit/kunit.py run --arch x86_64

No errors on

./tools/testing/kunit/kunit.py run --arch x86_64

I will try this again and let you know. Can you try this as well.

- Clean linux_next and run tests
- Run tests after buidling allmodconfig and mrproper

thanks,
