Description Pat Kane 2008-02-03 02:36:15 UTC 
Description of problem:
Xorg X server locks up, and sometimes the entire system hangs
after a "xrandr -o left" is done while mplayer is being used.

This is most likely related to "Bugzilla Bug 222818: Error in I830WaitLpRing()"

How reproducible:
Start mplayer running to display live video, using a HDTV 
file seems to cause the worst problems. Then do a "xrandr -o left".

Steps to Reproduce:
1. mplayer hdtv.ts
2. xrandr -o left
3.
  
Actual results:
X server dies, or hangs. Sometimes the 
system hangs without any message on 
a serial console.

Expected results:

Yeah, I know doing an xrandr while playing a video is a stupid 
thing to do... esp. since the video does not rotate with the
rest of the screen.   But it  is  also a bad idea to rotate
the screen and then play a video...
Comment 4 Pat Kane 2008-02-04 18:02:57 UTC 
Here is an interesting patch:
   http://lists.freedesktop.org/archives/xorg/2008-February/032634.html
    o_list is corrupted when we call i830_free_3d_memory. 
    This happens when the virtual size is > 2048 for non-965 machine and
    it causes X server segfault because the front buffer is not binded 
    when entering VT.

Should be fixed with the next -intel rebase.

Closing, intel driver in rawhide should have this sorted now.
