Description macro 2016-04-09 12:48:12 UTC 
After starting Xorg, interaction with the gui quickly causes the GPU to lock up with "ring 0 stalled for more than 10000msec" kernel messages.

Almost any GUI interaction triggers the lockup.  It's just a question of how long it takes, with interaction involving "more painting" triggering it faster.

The lockup does not occur as long as there is no gui interaction.  Just moving the mouse around does not trigger it.

This of course makes Xorg unusable on this system.

The Linux+Xorg stack did work reliably on this machine until early 2010, with reasonable 2D and 3D performance (for the hardware).  I did not use it between then and 2015, when I reinstalled an up-to-date version of Linux and Xorg stopped working.

The machine is, from uname -a, Gentoo "Linux 4.5.0-gentoo-r1" running on a "ppc 7400, altivec supported PowerMac5,1".

The video card is, from Xorg.0.log, an "ATI Radeon 7500 QW (AGP/PCI) (ChipID = 0x5157)".

Dmesg and Xorg.0.log attached.

Following are a few detailed examples of interactions triggering the lockup, with the resulting kernel error messages.

I am happy to follow instructions to provide more information.  I can probably also arrange SSH access to the machine.

Example 1: Drag a window

(start xorg)
(open a window and drag it, contents displayed while dragging)
(window drags a few centimeters, but very slowly)
(screen freezes, contents still shown)

Comment 6 Alex Deucher 2016-04-09 22:14:15 UTC 
AGP is pretty problematic on Macs.  Does disabling AGP (append radeon.agpmode=-1 to your kernel command line) help?

Hi Alex,

Disabling AGP (see attached dmesg and Xorg.0.log) improves the situation somewhat.

The system seems to survive more gui interaction now, but still fails consistently before long.  Examples below.

Prior to failing, screen updates seem accurate (in that there are no painting glitches) but are disappointingly slow.  To be expected in PCI mode?

Thank you for your assistance, Alex.  I realise this obsolete hardware is probably of little interest to you (or AMD), but it's a collectors' item to me and means a lot so I really appreciate it.

In this example, I discovered that moving the mouse triggers the "Saved ... dwords of commands" sequence, which otherwise occurrs every 30 seconds or so:


(start xorg)
(open a window e.g. terminal and maximise it)
(open another window e.g. file manager and drag it around in front of the maximised window for a few seconds)
(screen freezes with "tracers" of the last few frames of the moving window visible)
(exception information appears in Xorg.0.log similar to "Full Xorg.0.log (radeon.agpmode=-1)" attachment)

I have discovered that running

  Option "NoAccel" "True"

in xorg.conf "fixes" the problem, however I don't consider unaccelerated graphics an acceptable solution.

Does this in any way help narrow down where the real problem is?

Now as my problem in Bug 97987 is solved I am facing this bug with the radeon driver. I use a r300 card, but the error messages are very similar so I decided not to open a new bug. Unlike the original bug report I am running a current 4.8.1-kernel, xorg-server-1.18.4, xf86-video-ati-7.7.1 and mesa-12.0.3.

Having said that Bug 95017, Bug 91893, Bug 96519 look seem very similar.

Sometimes the GPU can reset itself, most of the time I get a hard lock. If I use "radeon-agpmode=-1" as kernel parameter, X on my G5 holds out longer, but sooner or later I get a hard lock too.

dmesg-output:

What I also got is some interesting output in Xorg.0.log via sshd from another machine. Maybe this is of some help:
