Yep, noticed this several days ago but haven't yet found time to investigate. > The changeset being tested last, as of now, and still failing, is: > db92aee2b477355759351889e37a365379b43bf6 I did notice the bisector ran and flagged commit 0f7436ca http://lists.xenproject.org/archives/html/xen-devel/2015-10/msg03385.html I've cc'd author of that commit.
