Staging looks fine, as far as my testing goes, and also according, e.g., to: http://logs.test-lab.xenproject.org/osstest/logs/105946/test-amd64-amd64-xl= -credit2/info.html Or: http://logs.test-lab.xenproject.org/osstest/logs/105900/test-amd64-amd64-xl= -credit2/info.html There appear to have been a problem, in a different test step, though, here: http://logs.test-lab.xenproject.org/osstest/logs/105919/test-amd64-amd64-xl= -credit2/info.html Which I noticed yesterday afternoon and am currently looking into it, because I don't see what has actually gone wrong. Also, looking at the history of Credit2 tests in 4.7-testing: http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-amd6= 4-xl-credit2/xen-4.7-testing Things were fine on=C2=A02017-02-16, and have started failing=C2=A02017-02-= 20. > Dario? >=20 I will investigate.
