[Pkg-virtualbox-devel] Bug#721786: virtualbox-dkms: Virtualbox netfilter modules don't work on Kernel 3.11

[manul]

Package: virtualbox-dkms
Version: 4.2.16-dfsg-2
Severity: important
Tags: patch

Dear Maintainer,

Upgrading to kernel 3.11 renders debian virtualbox package unusable.
Attempt to start virtual machines, results in an error message with regards to network (it suggests to manually modprobe vboxnetflt module; but it is already loaded).


Typical VBox log upon failed start VM attempt under 3.11 kernel:
--------

--------

The problem affects both Linux & Windows virtual machines, both 32 and 64 bit (no difference what virtual adapter was used).

Booting into a previous 3.10 kernel resolves the issue.

More info:

Exact problematic kernel which failed is 3.11-0.slh.1-aptosid-amd64.
The last kernel with which Virtualbox works fine is 3.10-10.slh.1-aptosid-amd64

aptosid is a sid-based Debian dfsg distribution.

aptosid's kernel maintainer advised to provide you the following related patch links from upstream:
