hmm, I wonder if it could be related to the termios changes in glibc
2.42 that landed in F-43. But there have been reports about apps
accessing serial ports being broken so far. There is an issue with
screen (not echoing typed text or similar) that I still need to look at,
but that came with the rebase to 5.0 in F-42 I believe.

Stephen, do you have more details? Because on a F-42 host I am getting
a working shell prompt when running
"podman run --rm -it fedora:43-s390x" (same with fedora:44-s390x)
