Downgrading the kernel to 5.15 from 5.19 was uneventful. make oldconfig worked fine without warnings, just a bunch of added drivers/features. Here the build system is building Glibc against the new Linux headers. The compile finished fine. You can see the chain of commands running locally on NoNIC within the QEMU VM (ssh into VM, bash, Deno run of build.js script that serves the web page on the left, runs the current shell command curr.sh, and finally make within glibc)
