** Summary changed:

- [hardy] Compositing + Xv causes SIGSEGV in memcpy()
+ [hardy] Xv causes SIGSEGV in memcpy()

** Description changed:

- Binary package hint: xserver-xorg-video-intel
+ Changed the Description for the ubuntu stable release team.
  
- Description:    Ubuntu hardy (development branch)
- Release:        8.04
- Arch: amd64
- Graphics card: i945
- xserver-xorg-video-intel:
-   Installed: 2:2.2.1-1ubuntu9~local1
- (a local build of ubuntu9 version, but the same problem appeared in earlier 
versions as well)
- 
- I'm running a KDE environment with the KDE3 compositing manager to get some 
nice transparent terminals.
- Sometimes when I try to play a video with Xv the server crashes in the driver.
- The crash causes the text-mode ttys to become unusable but a new X server is 
started by KDM.
+ 1. This bug is very critical, It causes the xserver to crash if you use XV (X 
video extension). In the worst case you lose data. Every open Application gets 
interrupted.
+ 2. This bug has been fixed thought a new driver version in Intrepid. To fix 
this problem in hardy I have applied an commit from upstream that fixes this 
problem ( 
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=commitdiff;h=1c0e4958564588162bc22a980567436dfc9d1e56
 ). I have attached a debdiff that I have created against the latest proposed 
xserver-xorg-video-intel_2.2.1-1ubuntu13.5 package. So far I could not find any 
bugs/problems that may have been introduced through this patch.
+ 3. You can reproduce this problem by playing some videos with totem (XV as 
backend). If you play a HD-Trailer the xserver crashes much earlier. If 
composite (compiz) is activated doesn't show any difference.
+ 4. As I mentioned earlier I could not find any new bugs. Two other people 
have tested the debdiff with success. I don't know if the Graphics Media 
Accelerator X3100 is also affected. I know that the chips from 915 to 945 are 
affected.
