dmesg after the fail

Apparently random GPU lockup (ati r300), with X.org freeze.

It happens more frequently if I compile and I switch over many applications
(firefox, terminal, opera). Attached there is the dmesg after the fail (I could
continue to work on others console - ctrl+alt+f1,2,3..).

Xorg log after GPU lock

It re-happens, so I saved also Xorg.log.

This happens with radeon.agpmode=-1 on the kernel boot command line. Without
it, the kernel doesn't boot (it freeze, without eth connection and monitor
freeze on some openfirmware specification - I have no serial - when switching
from openfirmware to kernel itself, I think).

How about agpmode=1? There's an issue with higher transfer rates that Ben
Herrenschmidt is working on fixing.

Created an attachment (id=38780)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=38780)
error with agpmode=1

When system load radeon modules with agpmode=1, I had this error (fortunately I
found it in /var/log/messages.log at next boot).

The lock happens more frequently, and give a black screen with no possibilities
to switch to another console. There isn't operations which cause this lock more
frequently than another: last time (this error) happens when I was scrolling an
Opera window.

Another thing, which happens both with -1 and 1: at time of loading modules
from my fs (yaboot->initramfs->my system->load modules) sometimes the kernel
freeze. I don't know where (unfortunately there aren't any log) but I think
it's related to radeon.
I need from 5 to 10 try to load properly and continue boot, otherwise I need to
force shutdown.

Uhm, black screen was here also with agpmode=-1, but I have no error message in
logs.
I was playing (for the first time) with GLX version of cairo-dock.
So now for me both modes doesn't do any difference :(

I'm not 100% sure (the radeon initialization output from dmesg could confirm),
but I suspect this is a duplicate of bug 28402.

Created attachment 54296
  --> https://bugs.freedesktop.org/attachment.cgi?id=54296
Dmesg crash

This also occurs to me on my system, a PowerPC 7447A PowerMac G4 with an ATI
Radeon 9800 Pro AGP (128MB). Using the packages from Debian Squeeze Backports
(7.10.3) with a near-Vanilla 3.1.0 kernel with radeon DRM modules built in
along with firmware.

However, for me it crashes about 10-20 seconds when glxgears is running, or it
instantly crashes when I attempt to move or resize a window in WindowMaker.

Setting agpmode=-1 fixes the problem for me.

Given your slightly different symptoms, I think we have to assume it's not
exactly the same problem. Please file your own report with all the relevant
information (at least dmesg output pertaining to agp/drm/radeon).

BTW, if you can narrow down where exactly in r300_asic_reset() the machine
check happens, maybe we can fix that.

FWIW, http://lists.freedesktop.org/archives/dri-devel/2012-January/017932.html
should increase the chance of recovering from a GPU lockup, or at least being
able to reboot cleanly, on a big endian host.
