Hi,

I'm currently trying to run Fedora 31 under qemu-user (https://github.com/fedora-cloud/docker-brew-fedora/tree/8a81f67271e959dfc8f8a888b161bbd540b7a83b/s390x) in order to debug a vector instruction issue.

Strangely, when trying to chroot into above rootfs and running /bin/bash, I get

t460s: ~/f31  $ sudo chroot . ./qemu-s390x  /bin/bash
TODO /home/dhildenb/git/qemu/tcg/tci.c:859: tcg_qemu_tb_exec()
/home/dhildenb/git/qemu/tcg/tci.c:859: tcg fatal error
Aborted


But it's not fundamentally broken:

t460s: ~/f31  $ sudo chroot . ./qemu-s390x  /bin/ls
bin   dev  home  lib64       media  opt   qemu-s390x  run   srv  tmp  var
boot  etc  lib   lost+found  mnt    proc  root        sbin  sys  usr


I do wonder why we don't run into the same issue under qemu-systems390x.

@Richard, any idea?
