Hi; qemu-system-s390x seems to have an intermittent failure at the moment -- it's been causing our Travis builds to flap. I actually caught it doing this on one of my local test builds (which happens to be aarch64 but I don't think that matters, since Travis is doing x86 builds):
while QTEST_QEMU_BINARY=s390x-softmmu/qemu-system-s390x QTEST_QEMU_IMG=qemu-img MALLOC_PERTURB_=${MALLOC_PERTURB_:-$((RANDOM % 255 + 1))} gtester -k --verbose -m=quick tests/boot-serial-test ; do true; done TEST: tests/boot-serial-test...
