I don't see anything obvious in the backlog. Is it possible to test a v4.1 kernel to see if this was fixed recently? In addition is this also present on PowerNV systems as well? ** Changed in: linux (Ubuntu) Assignee: Chris J Arges (arges) = (unassigned) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1443325 Title: ISST-LTE:Ubuntu15.04: task aio-stress:12277 blocked for more than 120 seconds.
