So let's make things easy. Attached please find my minimal config. This is what I use when I normally build a test kernels, and I get it by running "kvm-xfstests install-kconfig". I use it because it's fast to build, since it doesn't build extraneous stuff. I've also attached the "seb-config", which is your configuration with the minimal changes needed so it can run under qemu. The compressed size is twice as big, and it takes 2-3 times longer to build. I can't reproduce the problem you are seeing using kvm-xfstests using either kernel config building on 5.17. - Ted
