Does disabling AGP help? Load the radeon module with agpmode=-1
Indeed that solve the symptoms. I discover this was also documented here: https://wiki.debian.org/PowerPC/FAQ#How_do_I_get_graphics_working.3F [...] image=/boot/vmlinux label=Linux read-only initrd=/boot/initrd.img append="radeon.agpmode=-1 modprobe.blacklist=ams" [...] I am not sure what the 'ams' thingy is doing, but I am using it over here. The funny thing is that dragging window and moving them around makes the pointer and the window out-of-sync. Still usable though after a while. If AGP is simply not supported on PowerPC, it would be nice to have a clearer message (or at least a warning). Thanks
(In reply to Mathieu Malaterre from comment #3) > If AGP is simply not supported on PowerPC, it would be nice to have a > clearer message (or at least a warning). It is supported, it's just unstable on many PowerMacs. A patch disabling AGP by default on PowerMacs or even PPC in general probably wouldn't be rejected. :)

Should I submit it first on mesa-dev ?
FWIW on nouveau we just default agpmode=0 in a #ifdef __powerpc__. Perhaps the same thing can work for radeon.
(In reply to Ilia Mirkin from comment #7) > FWIW on nouveau we just default agpmode=0 in a #ifdef __powerpc__. Perhaps > the same thing can work for radeon. Well radeon_agpmode is already set to 0 already[*]. My patch force to PCI(-1) when user did not specify any value.

So in your case, just set it to -1 instead of 0 for powerpc. i.e. #ifdef __powerpc__ int radeon_agpmode = -1; #else int radeon_agpmode = 0; #endif or something similar.

I know about the coherency issues on some UniNorth bridges (DMA writes through the GART going directly to RAM, IIRC), but how did OS X cope with them? Did it also disable AGP transfers? If not, what can be done to fix this bug for real, instead of working around it? (I have a very vague memory that these hangs didn't happen before KMS, but I may be completely wrong.) Also, on a somewhat related note, there are still issues with the Radeon (R600, not SI) DRM on big endian, as for https://bugs.freedesktop.org/show_bug.cgi?id=95015. Thanks, Rui
Also been hit by this bug on 2 of my 3 machines: PowerMac 7,3 (A1047) w. Radeon 9600 Pro and PowerBook 5,6 (A1106). My PowerBook 5,8 (A1138) magically works with AGP! Which is interesting because both the 5,6 and the 5,8 use a Mobility Radeon 9700.

It seems the patches to force Radeon cards into PCI-mode (or force it via radeon.agpmode=-1) are no definitive solution. My G4 and G5 Macs hold out longer running X but sooner or later a hard lock is unavoidable. Tested this on a recent software stack: 4.8.1-kernel, xorg-server-1.18.4, xf86-video-ati-7.7.1 and mesa-12.0.3. See my comment at Bug 94877.
Played around a bit with xorg and kernel options on my G5 and worked out that I can drive the Radeon 9650 at AGP x8 if I disable DRI completely via Option "NoAccel" "true" in /etc/xorg.conf. I had no GPU-lockups since then and xorg is much more responsive despite lacking DRI hardware acceleration (radeon.agpmode=-1 with DRI enabled).

FWIW, the value of the radeon.agpmode parameter shouldn't matter if you disable DRI (which BTW means no GPU hardware acceleration can be used at all).

*** Bug 95177 has been marked as a duplicate of this bug. ***
Created attachment 142691 [details] dmesg I think I have the same error with my Radeon HD 4670 on x64_64 arch with linux, I attached my dmesg with the error in the end.
nothing seems to help, I tried agpmode=-1, disabling glamor that didnt help and Option "NoAccel" "true" wont let me login on the grafical user interface at all.
