Dmesg
I tried to use nouvear driver with acceleration on gentoo PPC64 running on Apple PowerMac G5, and failed with GPU lockup and segmentation fault. The linux kernel booted successfuly into a console, then the screen was filled with rubbish(colorful blocks or the like) and stuck there when I started "startx" in the console. After 5mins I pressed "Ctrl+Alt+F2" to switch to another TTY and succeeded, I got a message "nouveau E[ DRM] GPU lockup - switch to software fbcon". When I came again to the console X was launched, the X terminated and system fell back to the TTY with many errors(see dmesg and Xorg.0.log attached). This only happens when nouveau has acceleration, when I disable it by putting "Option 'NoAccel' 'true'" in xorg.conf, X and Gnome run normally without problems.
My computer is Apple PowerMac G5 of late 2003(PowerMac7,2) with GeForce 6800Ultra DDL graphics card(No any problem on Mac OXS 10.4.11). The followings are installed:
The linux kernel 3.12.0,
xorg-server 1.14.4,
mesa 9.1.6,
xf86-video-nouveau 1.0.10
