dmesg of PowerMac G5 Model A1047 with NV34 after crash

Hello!

I have recently performed a test installation of Debian unstable on a PowerMac
G5 (Apple Model: A1047) which exposed some reproducible crashes and rendering
issues with nouveau and the Apple-branded GeForce FX 5200 Ultra.

After installing Debian Wheezy which ships xf86-video-nouveau 1.0.1 I
experienced some serious rendering issues when starting gnome-shell 3.4.2.
After upgrading to Debian unstable which installed xf86-video-nouveau 1.0.9,
most of the rendering were gone. The version of gnome-shell was still 3.4.2 for
Debian unstable at that point.

With the driver from unstable, some minor glitches were still left. However,
the main issue was that it was possible to reproducibly crash the X server by
hovering the mouse over the applications menu of gnome-shell. This crash
produced some output in the dmesg buffer as well in the Xorg.0.log.

I am attaching all related log files and well as a dump of the video ROM of the
GeForce FX5200 Ultra used in this Macintosh. If you need further log files or
want me to perform some debugging, please let me know.

Cheers,

Adrian

--- Comment #5 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
I just posted a pair of patches that disable ARB_framebuffer_object on
nv30/nv40 cards. I believe that is the cause of this error:

[  254.402384] nouveau E[  PGRAPH][0000:f0:10.0]  ERROR nsource: DATA_ERROR
nstatus: BAD_ARGUMENT
[  254.402411] nouveau E[  PGRAPH][0000:f0:10.0] ch 3 [gnome-shell[2575]] subc
7 class 0x0697 mthd 0x0208 data 0x04060348

These should be "harmless" though (in that they'll just cause rendering to
fail, not apps to crash). You can grab the patches at

http://lists.freedesktop.org/archives/nouveau/2013-October/014671.html
http://lists.freedesktop.org/archives/nouveau/2013-October/014672.html

They should apply on top of mesa-git. Also, you didn't mention what version of
mesa you're using, but there's a nv30/40-specific bug in the 9.2.0 release
which is known to be triggered by gnome-shell. It is already fixed in mesa-git
on both master and the 9.2 branches.

However this:

[  258.941658] gnome-shell[2575]: unhandled signal 11 at 00000000 nip 0be2f384
lr 0be2f2d8 code 30001

appears to be a bug in gnome-shell (or one of its libraries... so I guess it's
possible it's in mesa/nouveau as well). Perhaps run it in gdb and look at the
backtrace? Or maybe it indicates some trouble in its stdout/stderr, not sure
where that goes in your setup.

Hi Ilja!

Thanks a lot for the detailed answer. The mesa version used was 9.1.6, 9.1.6-2
was the Debian package version.

What tests do you suggest? Should I build and install mesa from git with your
patches applied to verify that they fix the issue?

Cheers,

Adrian

Mesa 9.2.1 was just released today, try that. Although for the issue I was
talking about, I thought that it was only introduced in 9.2, and should not
have existed in 9.1, but perhaps I was wrong. Still worth a shot.

As I mentioned, logs from gnome-shell would be useful, as well as a full
backtrace when it crashes (preferably with symbols).

Alright, I'll try that.

Although the PowerMac is in a different office and currently MacOS X, I still
have the hard disk with Debian lying on my desk and I can simply pop it back in
and upgrade the packages.

We currently have mesa 9.2.0 in the experimental repositories, so I'll give it
a shot with that first, then upgrade to 9.2.1 from source and report back.

If gnome-shell still crashes, I'll get a gdb backtrace and post it here.

Don't bother with 9.2.0 -- that'll _definitely_ have some issues.

Ok, I recently made a dist-upgrade which fixed the gnome-shell crash issues.

The following versions have been installed:

- xf86-video-nouveau: 1.0.9
- libdrm-nouveau1a: 2.4.40
- libdrm-nouveau2: 2.4.46
- mesa: 9.1.6
- gnome-shell: 3.4.2

However, upgrading mesa to 9.2.1 from Debian experimental results in
gnome-shell failing to start.

I'm attaching the .xsession-errors of the failed attempt of loading gnome-shell
with mesa 9.2.1. I'll see if reverting mesa to 9.1.6 fixes the problem.

Yeah, I saw this as well after carefully reading xession-errors when the Mac
was already turned off.

The machine is in my office and I'm home already, however I have the machine
hooked up to my main machine now and have access to all files on the disk to
provide further log files maybe.

I had to shutdown the PowerMac since it's having issues with the fan control
when running Linux with the fans running at full power. It sounds like a jet
engine starting.

So, any specific logs you'd be interested in besides the output of glxinfo
(which apparantly needs the machine to be running)?

glxinfo with LIBGL_DEBUG=verbose

Now with LIBGL_DEBUG=verbose.

Looks like X is unable to load the DRI drivers. In fact, the DRI modules in
Debian are not available in version 9.2.1 like the rest of Mesa but in version
9.1.6 only.

Am I right that the version mismatch between the DRI modules and the rest of
Mesa is the reason why 3D acceleration is not working?

I have upgraded the kernel to 3.11-rc7 in the meantime, btw.

Doesn't have much to do with X, just mesa. If you don't have a nouveau_dri.so
file, you can't expect 3d acceleration to work, which I think in turn makes
gnome-shell rather unhappy. You also seem to be missing swrast, which is the
fallback, so libGL-related things are just totally buggered.

If you do have the file, you need to figure out why it's in the wrong
place/can't be loaded/etc.

Output of glxinfo for nv34 of PowerMac G5 Model A1047 with mesa-dri 9.1.7

Ok, after playing around a bit, I figured out that downgrading the
libgl1-mesa-dri package in Debian from 9.2.1 to 9.1.7 fixes the issue with
nouveau_dri.so not to be found and 3D acceleration and gnome-shell work as
expected again like it did with all mesa packages from unstable.

I guess it is an issue with the specific Debian package libgl1-mesa-dri from
experimental now and not mesa in general, even though the package actually
installs the nouveau_dri.so file at the expected location
(/usr/lib/powerpc-linux-gnu/dri/nouveau_dri.so).

I guess I wait until mesa 9.2.1 (or even 9.2.2) hits Debian unstable and I'll
try again.

Furthermore, I will also check the Debian bug tracker for libgl1-mesa-dri and
file a bug if necessary.

Cheers,

Adrian

Hi!

I am closing this bug report now since the original problem does not occur
anymore, as I already mentioned, after upgrading from Debian Wheezy (stable) to
Sid (unstable).

The problem with the DRI module unable to load is probably unrelated and an
issue with the Debian package for which an appropriate bug report in Debian
exists [1].

Adrian
