Bug Description

Binary package hint: xserver-xorg-video-intel

Crash which required reboot. The crash itself is described in https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/768176 and this is after I persuaded apport-gpu-error-intel.py to run.

My screen went entirely black (both laptop screen and second monitor). Switching to a VC did not show anything on screen. At first I could still hear sounds from running applications, but eventually (after ~10 seconds) they stopped. I had to powercycle the machine to get control back. The "system problem detected" apport dialog offered to let me file a bug, but then I got another crash dialog saying "apport-gpu-error-intel.py closed unexpectedly".

I have a suspicion this might be the same as or similar to bugs 767511 and 767425 - different error codes, but same chip and all are regressions that started within the past couple weeks it appears.

Let's let it freeze a couple more times, so you get a definite feel for the frequency and conditions of the freeze. Then, I want you to try booting to an earlier kernel from a week or two ago - prior to when you started noticing the freezes.

Hopefully you still have an old kernel installed; just hold down the left shift key during boot and it should let you select whatever kernels are already there. If not, you can install the older kernels from https://launchpad.net/ubuntu/+source/linux/+publishinghistory. For instance, to install the -8.41 kernel, go here:

https://launchpad.net/ubuntu/+source/linux/2.6.38-8.41/+buildjob/2429621

You'll want the linux-image-2.6.38-8-generic-pae deb; I don't think you will need anything else but if the installer complains you can snag other .debs as needed.

Forwarding this bug from Ubuntu reporter Stuart Langridge:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/768184

[Problem]
Infrequent gpu lockup on i965.

We've had a handful of reports in the last couple weeks of a gpu lockup on i965 systems which had not had freeze troubles for a long while (>6 months). Most reporters have experienced the freeze only once or twice; they don't know how to reproduce it, nor really have a way to definitively tell whether it is fixed or just occurs rarely.

I'm forwarding this report on the chance that the bug is a recognizable one to upstream; I don't think users are going to be able to pinpoint this down any further.

Bugs I believe to be dupes, all on i965 systems:

768184 IPEHR: 0x01800020
767511 IPEHR: 0x60020100
767425 IPEHR: 0x08000000
757968 IPEHR: 0x14000000

These i965 reports started coming in shortly after when we updated Ubuntu from xserver 1.10.0 to 1.10.1 and mesa from 7.10.1 to 7.10.2 and adding patch 25521900d to -intel (bug #35808). (Due to the intermittency of the bug I haven't had people try downgrading those packages.)

Bryce, one aspect that we are wary of with 965G[M] is that the early chipsets had severe issues with memory above 4G. It the memory configuration captured in the LP reports? The attached dmesg has 4G + PAE, is that common?

One affected 965gm user here (bug report with attachments https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/771655) - 4GB of memory but no PAE, ie. 64-bit. On the other hand my problem, is simply X.org crashing/segfaulting, I don't get apport triggered for a GPU lockup bug report. So sorry for the (possible) noise, even though my problem is clearly coming from the same bunch of changes and is similarly random/rare.

To make up for that, I went through the mentioned lockup bug reports to answer the question and: only two has PAE, four don't have PAE, but all those i965gm GPU lockup reports currently so far seem to be i686 unlike me.

I have been trying to get reproduce the bug to capture dmesg, i915_error_state and even backtraces from my gdm session, but I am not sure what triggers it yet.

So far, it seems that it freezes when the screensaver was running for some time BECAUSE IT HAD TURNED MY SCREEN OFF due to energy policy...

I had since disengaged the energy control option to never turn my screen off again, so far it has not frozen my system again. I suspect that this could be the root cause, but I am not sure how to prove it, or what packages could be involved to further the investigation.

It also seems to happen only on my systems with intel video boards (Mobile GM965/GL960 Lenovo Laptop and Mobile 945GME Express Asus netbook).

I think I may have reproduced this same bug on my own i965 finally. Not sure exactly how I did it, but it showed up after a lid open event (resume from sleep I guess). The machine has been plugged into its docking station with external monitor continuously.

$ cat /sys/kernel/debug/dri/0/i915_error_state
no error state collected

That's after a restart of the X server (Ctrl-Alt-Bcksp) so that I can access the machine again; I assume that would not reset i915_error_state?

The only indication in the logs I can see is in /var/log/Xorg.0.log:

[ 259.306] (WW) intel(0): flip queue failed: Invalid argument
[ 259.306] (WW) intel(0): Page flip failed: Invalid argument
[ 260.299] (WW) intel(0): flip queue failed: Device or resource busy
[ 260.299] (WW) intel(0): Page flip failed: Device or resource busy
[last two lines repeating]

These start occurring after I enable an output using xrandr (after a suspend/resume cycle); Xorg works for a while, but hangs immediately after I switch to a text console and back to X (a required action to actually see something via the new output, as per https://bugzilla.kernel.org/show_bug.cgi?id=24982).

A workaround that works for me is to modify xf86-video-intel to force intel->use_pageflipping to FALSE. I believe there used to be a user-accessible option to turn it off, but it's been removed? That is rather unfortunate, I must say.

Well, I guess all I can do at this point is sit and wait for that kernel bug to be fixed, hopefully some time soon; it's been open since last year... I'd be happy to try any patches you guys might have.

Potentially, either or both of these options in your xorg.conf might produce more detailed information in your /var/log/Xorg.0.log when these freezes occur. Also capture dmesg and /sys/kernel/debug/dri/0/i915_error_state from while the machine is locked (i.e., ssh into it over ethernet). All three attachments must be collected together at the same time, to ensure consistent data.

For what it's worth, with your patch applied, the kernel seems to crash less easily for me than without it.

bugzilla.kernel.org and that I'm currently unaware of any crash inside i915.ko, so you're going to have to remind me...

Chris, please see comment #19 in this bugzilla entry, or, for a complete description, see bug #37450. In essence, it seems that stale DPMS properties (kernel bug 24982), which normally just result in a blank screen, can in some situations result in a crash/hang. When I originally reported it I could only trigger it after suspend/resume; nowadays I can reproduce it just by repeatedly enabling and disabling an output a few times. The only workaround that works for me is modifying the xf86-video-intel driver to force page flipping off.

Not really, my intel devices have finally been working smoothly for a while
now... but the nVidia ones went bezerk with the proprietary drivers... a
whole other history, but very similar issue

Ok, I think we know that bug and had a fix for the races inside the page-flipping code, but I think Keith dropped them on the floor...

From the upstream bug, someone with this issue should install this test kernel and let us know if it makes the issues go away.

Per a recent request, I've built an Ubuntu test kernel based on the latest

Anyone still seeing this? I notice there hasn't been a dupe set in quite a while, and there's not been activity either here or on the upstream bug report in about a month. It does not look like the upstream proposed patch has reached the mainline kernel yet, although it's possible the bug got fixed some other way.

Thanks Colin. There's been several fixes to game-related lockups in the Intel mesa tree recently; I'll bet that did it for you.

Who else can re-test? I'd especially like to hear from anyone that had encountered the IPEHR 0x01800020 error.

Update to latest Ubuntu, and then play whatever 3D games you'd been playing previously. Play them for several hours at least, in case it's a rare issue on your hardware.

    drm/i915: Finish any pending operations on the framebuffer before disabling

    Similar to the case where we are changing from one framebuffer to
    another, we need to be sure that there are no pending WAIT_FOR_EVENTs on
    the pipe for the current framebuffer before switching. If we disable the
    pipe, and then try to execute a WAIT_FOR_EVENT it will block
    indefinitely and cause a GPU hang.

On my laptop (Lenovo X61s) the kernel provided in comment #59 did not make a difference. X still intermittently failed to resume with the page flip error in the log. I noticed that there had been a number of BIOS updates for my machine including one with a new Intel Video BIOS in version 2.18 (released 2008). After updating to the latest version, 2.22, I have not had a problem. New drivers are disagreeing with the old video BIOS on some behavior during resume I guess.
