Comment 33 for bug 532225

I think the automatic call for testing reached this bug report in error. What we really would like to have tested is an updated Lucid with the newest drm-intel-next kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/. This is not because we believe the bug is fixed there, but because those kernels have better debugging capabilities. See https://wiki.ubuntu.com/KernelTeam/MainlineBuilds for more information about the mainline builds.

WIth the newest drm-intel-next kernel, we would like a manual GPU dump after the hang. For this, openssh-server needs to be installed and another computer must be available to log in to the affected computer. After the hang, ssh in and copy the files /sys/kernel/debug/dri/0/i915_error_state, /var/log/Xorg.0.log, and the output of the command `dmesg`. If you filed one of the duplicate bug reports, attach the files there, since that makes it easier to keep track of which files come from where. See more information about this at https://wiki.ubuntu.com/X/Troubleshooting/Freeze#How%20to%20Get%20a%20Batchbuffer%20Dump%20%28-intel%20only%29 .

With this information, upstream will be able to look at it and we will get better understanding of how reliable the automatically captured dumps are (they have only been around for a short while, and we don't fully trust them yet, since there are a few things that may go wrong during the capture).
