It seems to hang forever in qos-test /arm/virt/virtio-mmio/virtio-bus/virtio-net-device/virtio-net/virtio-net-te= sts/announce-self : https://gitlab.com/huth/qemu/-/jobs/403472594 It's completely weird, I also added some fprintf statements: https://gitlab.com/huth/qemu/commit/8ae76c0cf37cf46d26620dd ... but none of them show up in the output of the test run... so I'm currently completely puzzled what might be going wrong here... Any other ideas what we could try here? Thomas
