@john This problem was meanwhile worked around by setting
radeon.agp.mode=-1 as default in recent kernels (=> 5.0 ?). So you don't
need to fiddle around with your settings here. Unfortunately Ubuntu ppc
support is dead, only ppc64le option is maintained.
But there are other distros (Void, Adelie).
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-

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

Yep. And I was astonished to see the desktop running faster actually. ;)

Tried to boot todays daily Yakkety iso on my PowerMac G5 7,3 which failed:
"Unable to find a medium containing a live file system" (see photo). Same
problem also for Lubuntu's daily Yakkety iso.
The same iso boots however on my PowerBook G4 5,6 + 5,8.

After a reinstall with an ext4 / partition I finally got a 4.8.0-rc4
mainline build running. At least there's no instant crash any longer.
The system was running for about 3 hours or so, but with some drm CP

Finally got around compiling a proper mainline Ubuntu 4.8-rc3 kernel.
Unfortunately it does not boot into my root partition due to an btrfs
error... So ATM no news if this freezing issue got fixed in more recent
kernels.

Ahm, well, had a look at http://kernel.ubuntu.com/~kernel-
ppa/mainline/v4.6-rc4-wily/. There is only a ppc64el PowerPC kernel. The
Apple G4 machines are 32bit, big endian. So I cannot test this latest

This issue also exists in Ubuntu MATE 15.10 PowerPC. I did not try
versions older than 15.10.
I will try the latest mainline kernel and report back as you suggested.

@Martin:
Thanks! As I suggested in the original bug description
"radeon.agpmode=-1" works as boot option. But as it's a bug and I didn't
find an up-to-date bug description I filed one. I am sure this affects
some more users of Apple PPC hardware.
Interestingly enough my Powerbook 5,8 is not affec

I am unable to run "apport-collect 1541151", because the iso does not
boot to a stage where network or file storage is accessible. I am
