Hardware: G3 Apple iBook, second gen.
fedora 18 version of the radeon driver. Downstream version is xorg-x11
-drv-ati-7.0.0-0.6.20120910git7c7f27756.fc18.ppc.
X starts up as normal first, but there is color distortions on gtk or
xlib based widgets. Light Qt apps seem to work all right if the system
is not pushed too hard. Example, Qterminal may stay for a few hours, but
starting a web browser makes X crash in a few seconds.
After a crash, xdm restarts X, but now, the colors all have strange
extra yellow tint.
Attachements: dmesg from boot till Xorg starts misbehaving. Some system
info, and Xorg.0.log.

Does booting with radeon.agpmode=1 or radeon.agpmode=-1 on the kernel
command line help?
BTW, it looks like the attached Xorg.0.log is from after xdm restarted
X? Can you also attach the log file from the first X server? It should
be there as Xorg.0.log.old after xdm restarted X.

Might add that except for the radeon driver, the iBook is stable.
Running X apps, even gtk and qt apps, works fine via X-forwarding over
ssh, and in a VNC session.

booted with nomodeset.
With this, the display seems stable again, and the color distortion is
gone.
So, does this mean that the problem is in the kernel or in the driver?
There are still problems with GTK widgets, but X widgets and Qt widgets
are fine.

There are several problems. The main one (probably in the kernel) is
that acceleration is not stable with KMS. Usually radeon.agpmode=-1
works around that, but for some reason it doesn't seem to on your
machine.
The second problem (probably in the X driver) is the wrong colours when
running on KMS without acceleration. I looked into this briefly a while
ago but couldn't figure out what's wrong.

I appear to have the same problem (inverted colours) on an early 2005 G5

ImageMagick's display seem affected; maybe Geeqie too. Firefox and Gnome
Terminal get their colours right, though. Everything seems usable
otherwise.

You're getting a GPU hang. Does radeon.agpmode=-1 help on the newer
kernel?

Actually, yes, it does. With radeon.agpmode=-1 the display is stable and
works quite well with GTK and QT apps. X widgets have distorted colors,
though.

At least, it worked for a few minutes lenger before locking up. When pushed a bit harder (firefox rendering a page while switching windows back and forth), it froze again like this:

Ignore that, that was with the 6.x driver. I'm now running the patches
mentioned in comment 14 and comment 15. With agpmode=-1, and it's stable
(2x glxgears, firefox, switching and flicking windows, no sweat), and
all the colors distortions are fixed, even on pure X widgets.
Has been running stable for 20 minutes now.
Hooray!

I just created version of the x11-drivers/xf86-video-ati-7.0.0 Gentoo
package in an overlay of mine [0] including the two patches mentioned in
comments 14 and 15. I built it, and it seems to work! The colours are no
longer inverted, and acceleration seems to be there (RADEON(0):
Acceleration enabled).
I haven't run it for long enough to know for sure about stability, but
from past experience, this setup already has passed the bumpy spot.

Well, the userspace accel drivers may be suffering from some bit-rot at
this point. I'd expect you may see similar issues even on x86 in
certain cases.

If you check your dmesg output you'll probably see a GPU lockup
reported. If you aren't already using radeon.agpmode=-1, try that,
otherwise, see comment 28.
