Bug#620480: I'm having random freezes on a GM965

[Jaime Alberto Silva <jaime@sgautomatizacion.com>]

Hello there,

I'm also experiencing problems with my Intel video card since the
upgrade to kernel 2.6.38. I have random freezes when watching videos
or editing them with Kino or Kdenlive.

The output of uname -a:

Linux inspironjaime2 2.6.38-2-amd64 #1 SMP Thu Apr 7 04:28:07 UTC 2011
x86_64 GNU/Linux

This is the card info from lspci:

00:02.0 VGA compatible controller: Intel Corporation Mobile
GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)

Here is the version of the driver, I'll see if I can upgrade to
unstable version and see if the freezing stops:

xserver-xorg-video-intel:
  Installed: 2:2.14.0-4

After the last freeze, while trying to watch a video, this is what I
found at the end of /var/log/Xorg.0.log.old :

Please let me know if more info is needed. Since this is a production
machine I'll have to go back to kernel 2.6.32 while this get fixed.

Thanks.
