http://www.gossamer-threads.com/lists/linux/kernel/1993181 reproduced by this http://www.kvack.org/~bcrl/20140824-aio_bug.c The bug was introduced by f8567a3845ac05bb28f3c1b478ef752762bd39ef and I believe it was fixed by d856f32a86b2b015ab180ab7a55e455ed8d3ccc5 I'm not certain if there were follow-on fixes after that. The bug is affecting Ceph OSD daemons, which hit this pretty reliably when using the new BlueStore backend. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- 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/1641129 Title: aio completions are dropped Status in linux package in Ubuntu: New Bug description: In 3.13.0-100-generic (14.04 stable kernel), we are hitting an old AIO bug, described in this thread http://www.gossamer-threads.com/lists/linux/kernel/1993181 reproduced by this http://www.kvack.org/~bcrl/20140824-aio_bug.c The bug was introduced by f8567a3845ac05bb28f3c1b478ef752762bd39ef and I believe it was fixed by d856f32a86b2b015ab180ab7a55e455ed8d3ccc5 I'm not certain if there were follow-on fixes after that.
