Package: linux-image-3.16.0-0.bpo.4-amd64
Version: 3.16.39-1+deb8u1~bpo70+1

I have experienced with randomly os freezing issue(no chance to ssh to it and investigate it immediately). It can be occured one time in a week or in a month. I didn't see any extremal load on server when hanging is occurred.

What I see in debian logs before the freeze:

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
