With the ccw ipl code sometimes an error message like "virtio: trying to map MMIO memory" or "Guest moved used index from %u to %u" appeared. Turns out that the ccw bios did not zero out the vring, which might cause stale values in avail->idx and friends, especially on reboot. Lets zero out the relevant fields. To activate the patch we need to rebuild s390-ccw.img as well.
