[hybrid snb-m-gt2 + GF106] libdrm assert hit in drm_intel_bufmgr_gem_init() because wrong kernel module was loaded

[Mehmet Akif TAŞOVA]

[Problem]
An assertion is hit in drm_intel_bufmgr_gem_init. We've had about thirty bug reports with this error. X crashes with this stack trace:

 __GI___assert_fail (assertion=0xb6f2df80 "0", file=0xb6f2e5ac "../../intel/intel_bufmgr_gem.c", line=2783, function=0xb6f2ebb7 "drm_intel_bufmgr_gem_init") at assert.c:103
 drm_intel_bufmgr_gem_init (fd=-1, batch_size=16384) at ../../intel/intel_bufmgr_gem.c:2783
 intel_init_bufmgr (intel=0xb85cfe08) at ../../src/intel_driver.c:409

The assertion appears to be catching a condition where the pci id does not match any known intel chip generation. Yet (in most cases), Xorg.0.log shows the system is indeed running on INTEL.

However, the system has two video cards. Either it's a hybrid (such as in this case), or it has an add-in card.

[Troubleshooting]
1. Run `lspci -vn | grep VGA` and verify that it shows two video cards.

2. Look in your /var/log/Xorg.0.log for mentions of which X driver is being loaded. The lines look like this:

  [ 16.675] (II) RADEON(0): blah blah

3. Run `dmesg | grep drm`. The messages will talk about whatever kernel driver it is loading up.

4. If dmesg mentions anything about "nvidia" or "fglrx", you have the proprietary video driver installed, and probably should uninstall and purge it first.

5. If it is discussing "nouveau" or "radeon", then the kernel is trying to load the wrong driver. Do any one of the following:

   a) For hybrid graphics: In BIOS look for a setting to disable the second video card and use it.

   b) Blacklist nouveau and/or radeon in your /etc/modprobe.d/blacklist.conf

[Xeletron (xeletron)]

As i also reported a bugreport about booting ubuntu without unity-panel and or black screen. In my search to get a workaround for this i found out that a reset of compiz and unity brought back a normal desktop. While an update of gnome or unity panel or ccsm with to much comflicting settings scambled the settings for compiz and unity. To do a unity and compiz reset i did the following: (regards to webupd8 website http://www.webupd8.org/2011/12/unity-3d-launcher-top-panel-doesnt-load.html)..

boot up, press CTRL-ALT-F1 and login.

To reset all the Compiz settings (this includes all the plugins settings, etc.) to the default values, open a terminal (don't run it with ALT + F2! The top panel and launcher will disappear after running the first command but will show up after the second one so use a terminal) and type:

export DISPLAY=:0.0

gconftool-2 --recursive-unset /apps/compiz-1
gconftool-2 --recursive-unset /apps/compizconfig-1
unity --reset

now log out and login again and unity is back.

..I hope this will give some help..

[M Khayron (coys)]

 i have tried suggestion from mr. ronald and it work. thank you for the information.

[Remco Brenninkmeijer (requist1)]

Happens regularly when I boot, compiz relaunches automatically and this error always goes with an error about an apt crash. Everything seems to be working fine after.
The black screen happened here also regularly but haven't seen that one for a little while now. (fixed by restarting lightdm or unity --reset)

[Remco Brenninkmeijer (requist1)]

the apt crash I mentioned might be unrelated but seems to always to go together with the one above. A fix for the apt crash has been identified:

I recently had a bug report get marked as a duplicate to this one. My bug was this

https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/982392

im not sure that its the same after reading the info posted in this bug report. I dont have compiz installed or unity.

Not sure what i should do next. Any suggestions?

[J Cord (j7cord)]

Hi Neon,

If you are running ubuntu 12.04 even if you are running gnome-shell, you
have compiz and unity installed.
To verify go to terminal, type the following two commands and note the
output.
unity --version ( that is unity (space) --(two dashes)version. You should
see the installed versions of unity and compiz.

Thanks,

Im running xubuntu 12.04. No unity or compiz installed. Running xfce.

when i type the command i get

The program 'unity' is currently not installed. You can install it by typing:
sudo apt-get install unity

[J Cord (j7cord)]

Hi Neon

I see, yes xubuntu is a great distribution. I love it. Unfortunately , if
my memory serves me correctly, there are numerous problems trying to get
gnome and gnome-shell to work properly within xubuntu 12.04 , at this point
in time. I can imagine that the reason you are getting the apport error is
the unmet dependencies which cannot be met within xubuntu. I have not
completely explored this assumption, however. You may try to google serach
for any newer information available on the web, to help you out. Please
also check that your machine meets the requirements to run gnome-shell if
that is what you are trying to accomplish. Good Luck.

Neon,
You are very kind, please excuse an old man, seems I confused you with

[NEON SAMURAI (n3on-samurai)]

No worries mate. :)

Thanks

[J Cord (j7cord)]

Dear Neon

I think this is what you are looking for , after reading Your !, message. (
again, sorry)

https://launchpad.net/ubuntu/+bugs

If you will follow that link, and then.
On the right hand side of your screen click on button and manually report
your bug. Stating that apport is mishandling the bug report. Hope this
helps.

Again, thank you, and Best Wishes ..

[NEON SAMURAI (n3on-samurai)]

Thanks for that. Done and done :)

[David Young (dove-young)]

I encounter this problem almost every day. I run Ubunut 12.04 with Gnome Shell on Thinkpad T400. I used an external display in office and have no external display at home. Almost everyday when I wake up my laptop from suspend at home, I got Ubuntu system encounter an internal problem.

I have to say it looks very very very like an Windows 98.

[Bryce Harrington (bryce)]

libdrm intel_bufmgr_gem.c has:

        if (IS_GEN2(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 2;
        else if (IS_GEN3(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 3;
        else if (IS_GEN4(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 4;
        else if (IS_GEN5(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 5;
        else if (IS_GEN6(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 6;
 else if (IS_GEN7(bufmgr_gem->pci_device))
                bufmgr_gem->gen = 7;
 else
                assert(0);

The crash is occurring because it's hitting that final assert. However, the intel graphics video card is a GEN6, and -intel is loaded on the system. However, there is a second (unused?) video card on the system. Presumably the code that retrieves the pci device id is getting the id for the wrong card?

There's your problem. The kernel is loading the nouveau kernel driver, but X is using intel.

Did you attempt to use vga switcharoo to turn on your nvidia card? If you did, undo that.

Otherwise, you need to blacklist nouveau.

[Bryce Harrington (bryce)]

I've updated the description with some troubleshooting steps.

Looking at some of the dupes, people are hitting this same assertion but with different system configurations. I would suggest everyone follow the troubleshooting steps first.

If toggling in BIOS does it, then there's not much we can do on the software side, at least for Precise.

However, if blacklisting the incorrect kernel driver solves it and makes Intel graphics stop crashing, that may be of interest to the kernel team. Undupe your bug report and update it with your findings, and we'll go from there.

[Bryce Harrington (bryce)]

ickle suggests recent ddx changes have prevented this assertion from getting hit.

[Chris Wilson (ickle)]

The problem here wasn't actually in the probe like I first thought, but lack of error checking in that version of UXA.

[Steve Langasek (vorlon)]

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
