dmesg of PowerMac G5 Model A1047 with NV34 after crash

Hello!

I have recently performed a test installation of Debian unstable on a PowerMac
G5 (Apple Model: A1047) which exposed some reproducible crashes and rendering
issues with nouveau and the Apple-branded GeForce FX 5200 Ultra.

After installing Debian Wheezy which ships xf86-video-nouveau 1.0.1 I
experienced some serious rendering issues when starting gnome-shell 3.4.2.
After upgrading to Debian unstable which installed xf86-video-nouveau 1.0.9,
most of the rendering were gone. The version of gnome-shell was still 3.4.2 for
Debian unstable at that point.

With the driver from unstable, some minor glitches were still left. However,
the main issue was that it was possible to reproducibly crash the X server by
hovering the mouse over the applications menu of gnome-shell. This crash
produced some output in the dmesg buffer as well in the Xorg.0.log.

I am attaching all related log files and well as a dump of the video ROM of the
GeForce FX5200 Ultra used in this Macintosh. If you need further log files or
want me to perform some debugging, please let me know.

Cheers,

Adrian
