This was a result of pushing a bad commit out, I have since found and fixed this. Just to clarify, you are testing all public heads? Or does head need to confirm to some naming scheme? Also, it seems you are testing in a KVM based VM, is that right? If so, including the kvm userspace (QEMU?) version and command line used could be benefitial in case people want to re-run the test.
