dri_debug.tgz

My Ubuntu lucid machine stopped booting recently. Instead of GDM I get a black screen with a horizontal multicolor 1 pixel line near the top of the screen. I hear the Ubuntu drum sound when it arrives at GDM though. I can login to the machine via SSH and I found a "GPU hung" error in dmesg. I captured batch buffers while hung (see attachment).

Via the Ubuntu GRUB "Recovery" option I was able to run an apt-get dist-upgrade from non-GUI mode and that installed a newer version of mesa (7.7-0ubuntu5) and that fixed my computer. I suppose one of the Ubuntu packagers also ran into this bug right after mesa 7.7-0ubuntu4 was uploaded and therefore uploaded 7.7-0ubuntu5 shortly after containing the fix.

The attached batch buffer might still be interesting for you guys? I'm resolving the bug though.
