Bug Description
In 3.13.0-100-generic (14.04 stable kernel), we are hitting an old AIO bug, described in this thread
http://
reproduced by this
http://
The bug was introduced by
f8567a3845ac05
and I believe it was fixed by
d856f32a86b2b0
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.
