dri_debug-20100227.tgz

Forwarding this bug from Ubuntu reporter takashi torigoe:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/475429

[Problem]
When compiz is enabled and a visual effect such as window movement occurs, the screen freezes.  A recent batchbuffer dump is attached.

A lot more discussion is on the downstream bug that I'm omitting since it looks less relevant.  Suffice it to say the issue has been tested to still occur with recent drm-intel-next kernels.

[Original Description]
Since upgrade to the 9.10 release, my screen freezes after visual effect (window move).
With visual effects disabled, there is no problem.
When freeze occurs, keyboard and mouse are unusable, but ssh login is OK.
So, I got Batchbuffer dump according to https://wiki.ubuntu.com/X/Troubleshooting/Freeze.
Dump is attached with this post.(dri_debug-20091105.tgz)

Operations
1. sudo INTEL_DEBUG=batch /etc/init.d/gdm restart
2. Set visual effects -> extra (compiz)
3. Window move by mouse operation.
4. Window swings (visual effect)
5. freeze occur
6. ssh & get Batchbuffer


I install the latest drm-intel-next kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2010-02-24/ .
And I got batchbuffer dump.
 sudo service apport start force_start=1
 mkdir dri_debug-$datestr
 sudo cp -r /sys/kernel/debug/dri/0/i915* dri_debug-$datestr
 sudo intel_gpu_dump > dri_debug-$datestr/intel_gpu_dump.txt
 dmesg > dri_debug-$datestr/dmesg.txt
 cp /var/log/Xorg.0.log dri_debug-$datestr/
 sudo cp /var/log/gdm/\:0.log dri_debug-$datestr/gdm.log
 sudo tar czf dri_debug-$datestr.tgz dri_debug-$datestr/

The batchbuffer dump is attached.
i915_error_state shows "no error state collected".
