Kernel OOPS netfilter 3.14.2

Kernel OOPS netfilter 3.14.2

[Florian Dörsch]

Hi,

I recently installed kernel 3.14.2 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.2-utopic/  <http://kernel.ubuntu.com/%7Ekernel-ppa/mainline/v3.14.2-utopic/>) since then, my computer crashes after a
while (mostly after 5-10h)

I have the display image (https://bugzilla.kernel.org/attachment.cgi?id=134401  ) of one of the kernel traces.

My hardware:
Intel i7 2600, 32GB RAM

My iptables rules:

Since the crashes are not recorded on disk/logfile, I can only provide that
image.

Thank you!

A bugzilla entry was created by me already:

But I was advised to write to the newsgroup instead
