[Problem]
Initially this looks like a false GPU lockup, because it seems to mask the error, but then there is a 'fixme', followed immediately by a render ring initialization failure. This appears to be going on during a resume from suspend.

This bug seems to be the crash that I sometimes get when I resume my laptop from suspend. Whenever I resume, the display will always turn on initially, usually with a still image from some framebuffer console. Usually, the X server will then come to life after a short delay (e.g. with the unlock dialog from gnome-screensaver). Other times, however, there is a longer delay, after which the display shuts off (blacklight and all). The rest of the system remains functioning, and when I log in via ssh, I'll find the reported error messages in the kernel log. The display remains inoperable even if I do an Xserver restart, a VT switch, another suspend/resume, or a hibernate/thaw. A soft reboot, however, does reset the display.

distro: Ubuntu 11.10 amd64
kernel 3.0.0-16-generic
libdrm 2.4.26-1ubuntu1
mesa 7.11-0ubuntu3
xorg-server 2:1.10.4-1ubuntu4.2
xf86-video-intel 2:2.15.901-1ubuntu2.1
machine: Lenovo Thinkpad R61 7733A82

I've had about fourteen of these crashes in the past month and a half, and I've managed to collect debugging logs on most of them. However, this bug has defeated all my attempts to deliberately reproduce it. Sometimes I go for almost three weeks with no hangs, other times I get several hangs in one day. This may be related to changes in my usage patterns (how frequently I use suspend, how much time I waste on Youtube videos, etc.), but I haven't found any correlation yet, nor do I have any real idea of what to look for.

Some observations I have made so far:
-) Doing many suspend/resume cycles in a row (e.g. running pm-suspend 50 times in a script) is *not* sufficient to reproduce this bug.
-) I once attempted to reproduce this bug by opening a large number of windows/applications at once, with the hope that this would stress the graphics system. However, it had no apparent effect on suspend/resume performance.
-) This bug does not seem to depend on the kernel version. I've encountered these hangs with the 3.0.0 kernel shipped with 11.10, and I've also seen it with vanilla 2.6.38, 2.6.39, and 3.2.0 kernels. However, I never encountered this bug when running Ubuntu 11.04 and its 2.6.38 kernel. It would seem that userspace changes are key.
-) This bug does not seem to be affected by the use of OpenGL compositing managers: the crashes continued even when I switched from Unity to Unity2D.

I'll attach some logs from one of my most recent hangs. I've added drm.debug=0x06 to my default kernel command line, which wastes syslog space but ensures that verbose logging is on when a hang hits. The kernel messages are from my syslog (from which I've pulled out irrelevant non-kernel messages). All of these logs were saved shortly after the hang (while I was logged in via ssh).

I've also set up some small scripts to collect logs and statistics with every suspend/resume, with the hope that this would help find what makes the difference between successful and unsuccessful suspends. Right now I only save dumps from xwininfo and xrestop, for lack of a better idea.

FWIW, I disabled DRI with
Option "DRI" "false"
in xorg.conf, but I still got a hang just now. That would seem to confirm that this regression is not related to the mesa driver.

This is still with the xserver-xorg-video-intel package shipped with Ubuntu oneric (2:2.15.901-1ubuntu2.1). I'll see about re-testing with updated versions of everything.

drm/i915: Only clear the GPU domains upon a successful finish

    By clearing the GPU read domains before waiting upon the buffer, we run
    the risk of the wait being interrupted and the domains prematurely
    cleared. The next time we attempt to wait upon the buffer (after
    userspace handles the signal), we believe that the buffer is idle and so
    skip the wait.

There are a number of bugs across all generations which show signs of an
overly haste reuse of active buffers.

Such as:

      https://bugs.freedesktop.org/show_bug.cgi?id=29046
      https://bugs.freedesktop.org/show_bug.cgi?id=35863
      https://bugs.freedesktop.org/show_bug.cgi?id=38952

      https://bugs.freedesktop.org/show_bug.cgi?id=41284
      https://bugs.freedesktop.org/show_bug.cgi?id=42141

    A couple of those pre-date i915_gem_object_finish_gpu(), so may be
    unrelated (such as a wild write from a userspace command buffer), but
    this does look like a convincing cause for most of those bugs.

Ok, somebody overwrite the ring-buffer. Just check you don't have the gallium-965 driver installed and try this patch which will hopefully catch the culprit.

Wait a sec... Does this hang almost immediately upon boot? I'd been assuming the values were reset due to a failure during the hang, but on the other hand, we might be not flushing the ringbuffer correctly.

As I described in comment 6, this is a hang that occasionally happens
immediately after resume from suspend.

I've applied the patch in comment 25 on top of v3.4-rc2-333-g668ce0a and
I am trying it now. It doesn't seem to have broken anything, but since
this hang is rare, unpredictable, and (at present) not reliably
reproducible, I can't say with confidence that the bug is fixed until
I've run it for at least a month.

All of my remarks in comment 6 still hold true. I'm still hoping to
find a way to quickly reproduce this, but at present, I know nothing at
all about computer graphics, so I'm stuck behind a huge learning curve.

OK, I am reasonably confident that the patch from comment 25 fixes this bug.

From April 14th to May 22ed, I made sure to use a kernel that contained
that patch, and I never had any post-resume hangs during that period.
As an experiment, I then reverted the patch, and it didn't take long to
get another post-resume hang. So the application of that patch strongly
correlates with the absence of these hangs.

Looks good to me. :D

Thanks for the report, Marcos. Does it hang happen every time you run
the game? I was not able to reproduce the hang that way, even without
the patch from comment 25. Of course, I have different userspace
(Ubuntu 12.04 amd64 with playdeb's ufoai) and different hardware (Lenovo
ThinkPad R61 7733A82).

Marcus, I expect that you have a distinct bug caused a defect in mesa trigged by the game. Can you please open a new bug and attach your dmesg, Xorg.0.log and critically the /sys/kernel/debug/dri/0/i915_error_state following the hang.

I'm seeing this bug on a compaq 6720s laptop after having upgraded the CPU from celeron-550 to core2duo t7100 half a year ago. It nearly always makes the laptop unuseable after logging in to a desktop environment (no matter which one).

Im running Fedora 18, specifically with kernel 3.9.6 and xorg-x11-drv-intel 2.21.8. libdrm 2.4.45, xorg-x11-server-Xorg 1.13.3 .

Bjorn, that is a completely different bug and looks just like a common mesa bug.

Damian Christey, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

I have not encountered this bug in a long time, and I believe that it is fixed in the kernel as of upstream commit 3eef8918, which is included in v3.5 and later. The fix was backported to v3.2.y kernels with commit 71583724, which is included in v3.2.21 and later.

So, quantal and later have the fix because they use kernel v3.5 and later, precise has this fix because it tracks the upstream v3.2.y stable kernel, and if my memory is correct, lucid was never affected by this bug. So, this bug no longer affects any supported version of Ubuntu.
