Package: linux-image-3.16.0.4-amd64
Version: linux-image-3.16.0-4-amd64
Severity: important

Dear Maintainer,

   * What led up to the situation?
The computer contains an intel processor with 2 digital outputs. If I want to use both outputs,
the intel driver crashes. The second display stays blank, the display is starting over and over.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Swapped the displays, same result. Tried different xorg-configurations, no change.

Here is an extract from the kernel-log:

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
