I can also replicate the problem on current master. I can solve it by building master with --disable-linux-io-uring.
I also tried building Linux 5.4.39 where the issue happens too: Linux cc 5.4.39qemu #1 SMP PREEMPT Sat May 9 12:11:38 CEST 2020 x86_64 GNU/Linux
I attached the logs of that latest run.
