This is very interesting, I'll give a try.

However I would like to know if the problem is Hardware, Software 
(Kernel) or Software (another program).

I see that line in the report :
[1639377.680513] CPU: 2 PID: 2618 Comm: pgld Not tainted 
3.16.0-4-686-pae #1 Debian 3.16.7-ckt9-3~deb8u1

Does this mean that pgld is the process which generated the Divide Error 
?
Pgld stand for PeerGuardian Linux : 
http://sourceforge.net/projects/peerguardian/files/PeerGuardian%20Linux/

PeerGuardian Linux is a privacy oriented firewall application. It blocks 
connections to and from hosts specified in huge blocklists (thousands or 
millions of IP ranges).

I've checked the debian repo.
The most recent kernel available is 4.0.0.2.

I assume I'll have to wait for that patch...

It looks like that patch has already been applied to the latest Debian
4.0 kernel (as has the other fix mentioned in Leon's link,
c72efb658f7c)

So give it a try :)
