Hi,
I've been experiencing tainted kernel which is my guess caused by postgresql and I don't know where to start. I also guess that this might be a kernel issue. I tried 3.13.0-49 and 3.13.0-53 but no good results. This is happening on 2 of our Ubuntu 14.04.2 servers with postgresql-9.3 version 9.3.5-0ubuntu0.14.04.1. I am also using the same postgresql version and kernel to other 10 14.04.2 servers and doesn't seem to encounter this problem. Below is the kernel log:
