Bug#497116: xorg: random crashes on shutdown

[Sten Heinze <sten.heinze@gmx.de>]

Hi, 

I was not able to attach gdb successfully in case of a crash. Trying to attach 
after a crash is not possible (ssh: connect to host 160.129.138.82 port 22: No 
route to host). Everytime I attached gdb before shutting down, it did not 
crash.

So I tried to change kernel version (vanilla 2.6.25.10 to 2.6.26.5), but 
crashs still occur. I also tried to test the new xorg (xorg 7.4~3, xserver 
1.5.0-1, xserver-xorg-video-intel 2.4.2-1), but I was stopped by bug #497267 
(underrun on pipe B!).

Let me know, if I can help further than trying to get a backtrace.

Thanks,
Sten
