Stefan, this seems to be caused by your patch "virtio-pci: use ioeventfd
even when KVM is disabled". I can reproduce it on x86_64 under valgrind.

QTEST_QEMU_BINARY="valgrind x86_64-softmmu/qemu-system-x86_64" \
tests/virtio-scsi-test -p /x86_64/virtio/scsi/pci/scsi-disk/unaligned-write-same

I'll drop the patch from my queue for a v2 pull request.
