The qcow2 test is one of the only ones I'd expect to be exercising gntdev (most tests use LVM+blkback), which explains why this particular commit is apparently seeing issues due to this particular change. From these ... http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qcow2/linux-3.14.html http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qcow2/linux-3.16.html http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qcow2/linux-3.18.html http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qcow2/linux-4.1.html http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qcow2/linux-linus.html ... it seems only 3.14 is hit, I wonder why? Maybe the other stable trees haven't gotten this yet (or osstest hasn't gotten to a revision with it) but linux-linus certainly will and it appears to be fine there. Perhaps a mis-applied/behaving backport or a missing associated patch? Flight 60952 on linux-linus was on huxelrebe0, contained 30b03d05e0746 and passed. That is the same h/w as huxelrebe1 which is failing (sticky) on 3.14. Also 60785 on linux-4.1 was on huxelrebe1 itself and contains the backport, and was fine. So I conclude it is probably not a h/w specific issue.
