Description Oscar 2011-09-01 12:31:41 UTC
As in title, the driver freezes my wheezy system apparently in random way,
more times when in fullscreen mode (such as xscreensaver)
but also in normal screen mode. Then i'm forced to brutally shutdown and reboot
but this
can cause hardware problem in the future so i want to stop with this procedure.
The old
stable driver version 2.13 doesn't work properly on my chipset, probably
because of incompatibility
with the new chipset. Both versions 2.15 and 2.16 (from git of
intellinuxgraphics) of the driver have the same problem.
Switching to vesa yields stability but also unusefulness of many applications
that require
hardware acceleration, so it's usable only for text processing and other low-
resource-needed
apps. Fbdev driver doesn't work for me, so that's the empass. No useful errors
are reported in
kernel or Xorg logs.

Comment 1 Chris Wilson 2011-09-01 12:39:08 UTC
The first bit of information I need is whether this is a GPU hang. Is the system accessible after the freeze and is /sys/kernel/debug/dri/0/i915_error_state populated?
Comment 2 Oscar 2011-09-01 13:57:20 UTC
The system is totally unaccessible after freezing, even with standard console key combinations (Ctrl-Alt-F*)
that's the reason for the brutal shutdown. The file /sys/kernel/debug/dri/0/i915_error_state reports
"no error state collected" for the time being, but i've rebooted and uninstalled intel driver, so dunno
if it's overwritten by the new system bootup.

Ok, my guess is that this is https://bugzilla.kernel.org/show_bug.cgi?id=27892 in which case adding an Option "DebugFlushCaches" "True" to the Device section in your xorg.conf (or add a snippet to xorg.conf.d if you prefer) will workaround the bug.
Comment 4 Oscar 2011-09-02 01:38:25 UTC
But i get no error messages in the kernel after the freeze.
Anyway, if i have to follow your suggestion, should i also add that patch
in the bug you linked me to, to the driver?

Comment 5 Chris Wilson 2011-09-02 02:10:45 UTC
No, the xorg.conf option is sufficient. The patch was simply to hardcode the workarounds for a distro pkg.
Comment 6 Oscar 2011-09-02 04:03:51 UTC
Nothing to do.
I followed your suggestion but the system still freezes, this time even in normal screen
mode (no xscreensaver running). Here's my /etc/xorg.conf.d/10-intel.conf:

Section "Device"
  Identifier "PCI:00:02.0"
  Driver     "intel"
  Option     "DebugFlushCaches" "True"
  Option     "DebugFlushBatches" "True"
EndSection

The driver version running is 2.15 from debian wheezy package xserver-xorg-video-intel, kernel 2.6.39 .

I am getting the same behavior on a Thinkpad like Oscar, so Chris, I'll turn on the extra settings and hopefully get some information on where this is happening.

The mouse pointer freezes, and not even the raising elephants key combos work. I did not try to log in over the network however.

Setting i915.semaphores=1 on the kernel command line seems to fix this issue on my T420. Apparently Debian and Ubuntu also have or are in the process of releasing an update to their distros that fixes some lockup issues.
Comment 10 Daniel Vetter 2011-09-30 13:09:58 UTC
Please attach the full dmesg after boot and grab all the i915 kernel module parameters (i.e. all of /sys/module/i915/parameters).

Also please boot with i915.reset=0 (this sometimes prevents a gpu hang from taking down the complete systems), rehang your machine and try to grab as much as possible. Also check /var/log/messages in case the machine still hard-hangs, maybe something hit the disk.

Please describe your describe your desktop enviroment, like what window manager you're using and whether you have enabled/disabled compositioning. And add the version of your mesa package, please.

Thanks, Daniel

Hi

I am not the original reporter but I believe I am experiencing the same issue (lenovo x121e, 00:02.0 VGA compatible controller: Intel Corporation Sandy Bridge Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]))

The environment is gnome 2.30 as shipped wth debian squeeze (metacity window manager) and using xserver and intel driver backported from wheezy (xserver-xorg-video-intel: 2.15.0-3~bpo60+1).

In most cases nothing is found in the logs but four times (out of maybe 10 or 15 lockups) the last lines of syslog were:


...

Thanks!

Could you attach the /sys/kernel/debug/dri/0/i915_error_state as well, when the issue happens?

It should help to narrow down where it comes from..
Comment 16 maurizio 2011-11-07 14:41:54 UTC

Unfortunately even when booting with i915.reset=0 I can't access the system without rebooting and nothing is found in /sys/kernel/debug right after reboot.

This option did not bring any additional information to syslog either (yet).
Comment 17 delete 2011-12-11 12:30:34 UTC
In addition to bug 43587 I have this bug too. I have disabled the new sna-code and disabled dri in my xorg.conf for testing, but my system freezes from time to time. My system is current useless because the intel-driver freezes my system and the vesa-driver don't work (black screen).

I tried the following too:
DebugFlushCaches and DebugFlushBatches in xorg.conf
i915.reset=0 or i915semaphores=1 in kernel command line
login over network and ssh - no response

I can't upload the i915_error_state because the only way is to reboot my system. :(
How can I help to supply you with more information?
Comment 18 maurizio 2011-12-11 22:02:53 UTC
In an attempt to get more information I added this line to my crontab: 

*/1 *   *   *   *       cp /sys/kernel/debug/dri/0/i915_error_state /home/tester/tmp/debug/i915_error_state"$(date)"

but when the machine hangs this line is not executed anymore and the last version of i915_error_state just contains "no error state collected".

The only additional information I can provide for now is that altough neither the kernel nor xorg have been updated since my last communication about this bug, the machine now hangs *much* more seldom. It used to be several times a day at that time, sometimes within minutes of booting and that several times in a row, while it did not happen anymore for weeks.

Is there anything else I can try to grab this i915 error state?


Thanks,

> No idea to get debug informations like i915_error_state.

http://intellinuxgraphics.org/how_to_report_bug.html has some instructions on how to get them.

But for this specific issue, could you try with kernel 3.2-rc6? It should enable semaphores on the system by default (unless you have I/O virtualization).

Also, as there is no easy way to get the i915_error_state, and machine locks hard, if you could setup netconsole to get kernel messages over the network it would be very helpful (for example, as explained here - https://wiki.ubuntu.com/Kernel/Netconsole).

Xorg.0.log with crash, dmesg with black screen

If I'm booting kernel 3.2.0, and the graphic driver is changing the
resolution, I get a black screen (modeset?).
The System itself is running normal in the background. Which means I
can type "blind" or login with ssh (see dmesg output at attachment).
Also the system is booting up properly with the parameter "nomodeset".

There were no errors with kernel 3.1.5.
(So I think the bug lies between version 3.1.5 and 3.2.0.)
Maybe somebody with a Sandybridge Mobile (GT2) graphics card could
test it, to exclude errors in my kernelconfig?

I've made the following changes:
mesa 7.11 -> 7.11.2
kernel 3.0.6 -> 3.1.5
xf86-video-intel git version (19.12.2011)

But there is something positive to report:
Instead of freezing the complete system, it's "only" the xserver that
is crashing.
This makes it possible to login per ssh and kill the xserver.
If the server crashes always the same error message appears in the logfile:
kernel: [drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH

Now I'm using xf86-video-intel git version (09.01.2012)...

Comment 27 Graeme Russ 2012-01-24 15:36:37 UTC
I think I have a similar issue, so I won't create a new bug report just yet

My configuration:
 - ASRock Z68 Pro3 Gen3 Motherboard
 - 8GB RAM
 - Intel i5 2500K
 - Vanilla 3.2.0+ kernel (Commit ccb19d263fd1c9e34948e2158c53eacbff369344)

I've tried logging via Netconsole but no additional messages appear there which aren't already in /var/messages

i915.semaphores=1 does not help

Using an nVidia PCIe card and unloading the i915 modules at least allows my system to run stable

Am willing to do do whatever compiling, logging, testing etc necessary to help figure this out

Comment 31 Peter Tworek 2012-03-15 13:32:20 UTC
I think I'm affected by exactly the same problem as described in this bug report. In my case the easiest way to reproduce this issue is to run Oblivion under wine. The problem happens few seconds after loading any save game. What is interesting is the fact that my system somehow manages to recover and after the initial freeze it continues to run the game for another few seconds. After that another freeze occurs. During the freezes I'm usually able to switch back to virtual terminal to kill Oblivion.exe process to collect some debugging data.

What I've been able to deduce so far is that this is an regression in either mesa or libdrm. When using mesa 7.11 from git (906f670f1a1f33d69139f520ee931b268049eac6) with libdrm 2.4.27 the game runs without any problems. Tried this combo on both kernel 3.2.11 and 3.3.0-rc7 and the results are the same. No hangs, dmesg is error free. When moving to mesa-8.0 (b9f8cb9e0b1bd640b9b362c9ad56791e4c8cabcd) + libdrm-2.4.31 (tar.gz version) the problem with GPU hangs manifests itself. I even tried the latest mesa and libdrm from master branches and the result is the same, GPU hang. Kernel version, i915 module options don't have any effect, the hang still happens. I'll try to bisect mesa from 7.11 to 8.0 maybe I'll find specific commit which introduces the problem.

    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=35863

      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.
