I installed vmlinuz-4.20.0-042000rc3-generic per your request. The machine won't boot, and just loops infinitely with the error message:
request_module: kmod_concurrent_max (0) close to 0 (max_modprobes: 50), for module binfmt-646c, throttling... request_module: modprobe binfmt-646c cannot be processed, kmod busy with 50 threads for more than 5 seconds now I've done some googling and don't see an obvious fix.
