Looking here: http://logs.test-lab.xenproject.org/osstest/results/history/test-armhf-armh= f-xl-credit2/xen-unstable It seems to be happening only on the cubietracks, but in a non-linear and non-deterministic fashion. E.g., 113791 failed on metzinger, which is fine on 113800; 113611 and 113618 failed on baroque, which is fine on 113638. I don't see much in the logs, TBH, but both `xl vcpu-list' and the 'r' debug key seem to suggest that vCPU 0 is running, while the other vCPUs have never run... like it was an issue with secondary (v)CPU bringup. It indeed shows up with Credit2, as it were _specific_ to it, but I'm not 100% sure. In fact, it indeed seems to never show up here: http://logs.test-lab.xenproject.org/osstest/results/history/test-armhf- armhf-xl/xen-unstable but it looks like it may have shown up in 112460 (but we don't have the logs any longer): http://logs.test-lab.xenproject.org/osstest/results/history/test-armhf- armhf-xl-cubietruck/xen-unstable So... ARM people? Does this ring any bell? Is this something known, or easy to explain? What can I do for help?
