Bug Description

When i run my Ubuntu server over night I often wake up the next morning to the error message:

"unable to handle kernel null pointer dereference"

If I reboot the server then it works fine for a couple of hours at least but then i see the error message again the next day.

I have attached a screen dump of the error message.

Please let me know if you need more information

Hi Joseph,
I have been running previous version of Ubuntu were I have never experienced any problems on with the Kernels. However that was on an NVIDIA ION mother board with an ATOM processor (about 6 years old).
I have now bought a new ASROCK Q1900-ITX motherboard with an integrated Bay Trail ATOM processor. And it is the first time I install the Ubuntu 14.04 64 bit release on it so I have not tried out any previous Ubuntu releases on this hardware.

HI Joseph,
I can try out the latest Kernel. I just tried to follow the instructions for replacing with the proposed Kernel and it looks like Aptitude is replacing the Kernel.
But afterwards when I run "uname -r" it claims that I still have the old Kernel installed: 3.13.0-36-generic
I don't know how to replace the Kernel then.

Yes but it does not seem to work. The kernel may not have been replaced.

If I use the other method "apt-get"‎ to replace the Kernel what package name do I need to use?

Hi Joseph,
So the new Kernel (3.13.0-37-generic) basically came in during my latest update about a week ago and my server has been using it since then.
However, I'm still getting the Kernel Crashes.
I have found out that there is a correlation between the kernel crashes and a daemon that I'm running sabnzbdplus which is a newsgroup downloader. If I don't download anything with it and just let it sit idle in the background then the Kernel can run for days without crashing. As soon as I make the daemon download something overnight I wake up to a crashed Kernel.
From the crash screen I noticed one of the lines:
CPU: 1 PID:24790 Comm: sabnzbdplus Tainted
I can understand that there potentially could be some bugs with sabnzbdplus but I don't understand that it can take down the whole Kernel.
Best RegardsTommy
