Bug#597664: linux-image-2.6.32-5-686: Xorg crashes with radeon kernel messages
 
Package: linux-2.6
Version: 2.6.32-23
Severity: important

Today I had a very special issue with my workstation. The display would
start but freeze. Even though in the back things are still happening,
the display isn't updated and the only way out is to go to TTY1
(control-alt-F1) where the console gets flooded with messages like this:

Sep 21 17:59:04 lenny kernel: [ 102.324219] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(0).
Sep 21 17:59:04 lenny kernel: [ 102.354242] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
Sep 21 17:59:04 lenny kernel: [ 103.124761] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(1).
Sep 21 17:59:04 lenny kernel: [ 103.155110] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
[...]

(The message loops through IB(0) to IB(15).)

Stopping gdm (invoke-rc.d gdm stop) stops the warning, but restarting
gdm doesn't fix the display (in fact it doesn't affect the display at
all) and the messages come back.

Oddly enough, sometimes, things "just work" without an hitch: it seems
that the issue is intermittent. The problem mostly happens when I logout
and log back in quickly. I have recently upgraded sid twice, once on
august 11th (when xorg and linux-image were upgraded) and once today (to
try to fix the issue). However, things were working well *after* the
august 11th upgrade as far as I remember, so I am unsure when the
regression got in. I first noticed the behaviour today *before* the
upgrade.

The only other change on this machine is that I switch from an old 15"
CRT to a new Aceer X193w LCD monitor. I also tried to fiddle with
subpixel rendering and anti-aliasing in the fontconfig-config package
yesterday, although I fail to see how this would be the cause of this
issue.

I have tried numerous workarounds I could find on the internet
(references below):

[1] disables modesetting, by editin /etc/modprobe.d/radeon-kms.conf to:

options radeon modeset=0

no luck: display still freezes, and instead the load goes up and up and
I can't kill X at all.

[2] sets the AGP mode, in the same file. no luck either there.

[3] suggests upgrading to a later version of the kernel, which here
just crashes the whole machine: total freeze, no display, no keyboard,
only a cold reset brings back the machine.

[4], [5] and [6] also point to similar workarounds which either do not
work or do not work for me. Most end up pointing to the kernel as the
culprit.

Indeed, [7] is the bug in the kernel itself, which is announced as
resolved, but I am not sure if this is in experimental yet.

Based on the above evidence from third parties and the fact that the
error comes from the kernel (and not X), I am reporting this against the
kernel.

Thanks,

A.

This points to disabling modeset as a workaround.

[2] http://bugs.debian.org/585815 suggests to play with agpmode=1

[3] http://bugs.debian.org/588688 suggests upgrading to 2.6.35~rc2. I
tried 2.6.35-1~experimental.3 and it crashes.

issue

kernel and KMS, with no clear workaround or fix.

[7] https://bugzilla.kernel.org/show_bug.cgi?id=15969 is the upstream,
closed kernel bug, fixed on 2010-06-13. Unclear if this is 2.6.35.

Could you elaborate on that? By "crashes" do you mean it produced the
same symptoms or did something else?

That bug points to v2.6.34-rc7~6^2~11 (drm/radeon/kms: r300 fix CS
checker to allow zbuffer-only fastfill, 2010-04-13) as cause and
v2.6.35-rc1~18^2~6 (drm/radeon/kms: release AGP bridge at suspend,
2010-05-21) as a fix, so I suspect it's a different bug.

Also, because it's been so long, I ought to ask:

- can you still reproduce this with recent sid and squeeze kernels?
- any ideas, weird symptoms, or workarounds discovered since then?
How have you been coping?

Hope that helps,
Jonathan

No, as the hardware is offline.

I have gotten rid of that device. I may rebuild it at some point, and
I'll get back to you if I can! :)

Thanks! Marking so heroes of bug reproduction and log interpretation
can know their work is appreciated in the meantime.
