Public bug reported:

Binary package hint: xserver-xorg-video-intel

xserver-xorg-video-intel does not have support for Sandybridge Xv video
acceleration, but it advertises support and attempting to use it is
causing a system hang. Given that these devices will be released before
11.04 is released, I believe it would be in our best interest to disable
Xv for Maverick for a better user experience. The change only affects
these specific devices (covered by the IS_GEN6 macro) so the regression
potential is extremely low.

video: Disable TextureAdaptor for Sandybridge
The acceleration code does not yet exist, so we try to use gen4 shaders
which hangs the chip and makes everybody upset. Disable it until such a
time as support is written for Sandybridge XVideo.

Patch will follow soon and has been tested by me on 2 sandybridge machines to verify that desktop applications that autodetect Xv support no longer crash the system (cheese, totem visualizations, rhythmbox visualizer).
