I was not able to reproduce this issue so far (on my x86 laptop since I
don't have an aarch64 host) ... can you reproduce it by running the test
directly, too, e.g. something like:
QTEST_QEMU_BINARY=s390x-softmmu/qemu-system-s390x tests/boot-serial-test
?

Or could this be a timeout issue again? Is the host very loaded?
(however, I don't really believe that this could be the issue here,
since the test is rather fast)
