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
