Package: linux-image-5.6.0-2-s390x
Source: linux
Version: 5.6.14-1

5.5 worked correctly:

# qemu-system-s390x -M s390-ccw-virtio -cpu max -m 512 -kernel vmlinuz-5.5.0-0.bpo.2-s390x -display none -serial mon:stdio
qemu-system-s390x: warning: 'msa5-base' requires 'kimd-sha-512'.
qemu-system-s390x: warning: 'msa5-base' requires 'klmd-sha-512'.
KASLR disabled: CPU has no PRNG

But 5.6 appears to stop immediately:

# qemu-system-s390x -M s390-ccw-virtio -cpu max -m 512 -kernel vmlinuz-5.6.0-2-s390x -display none -serial mon:stdio

# echo $?

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
