agpgart-intel not loaded before drm sometimes, causes KMS to fail

[Kai Jauch]

On some boots drm gets loaded before agpgart-intel, which causes drm to fail. KMS then is not available.

Here, my work around for the issue has been to set the following in /etc/initramfs-tools/modules:

# List of modules that you want to include in your initramfs.
#
# Syntax: module_name [args ...]
#
# You must run update-initramfs(8) to effect this change.
#
# Examples:
#
# raid1
# sd_mod
intel_agp
i915 modeset=1

Once this has been configured, you need to run:

sudo dpkg-reconfigure linux-image-2.6.31-10-generic

[Louis Simard (louis-simard-deactivatedaccount)]

The workaround from comment #2 worked here, thanks :)

[Jonathan (jonathan00)]

hi,

today i upgraded karmic. a new kernel came with that, linux-image-2.6.31-11-generic. After some rebootings, i suddenly got this error. before not.

the woraround from #2 helped me, but with changes:
...
intel_agp
 i915 modeset=0

Once this has been configured, you need to run:
sudo dpkg-reconfigure linux-image-2.6.31-11-generic

[Jonathan (jonathan00)]

some more infos, without workaround, xorg takes 100% cpu, so it it not easy to use the system anymore ;-)

kde,i386, Intel 82852/855GM

[laborg (gerhardtt)]

has anyone got a clue why this only affects every Xth boot?

[Jonathan (jonathan00)]

with the workaround, it also worked for me with i915.modeset=1 set to grub. But with the last kernel-update i run again in the error. workaround wasn't working for me. at the end, this helped me in /etc/initramfs-tools/modules

...
fbcon
intel_agp
agpgart

i think fbcon is not needed anymore, was another workaround for black screen

>has anyone got a clue why this only affects every Xth boot?
i think the problem is, when initrd gets updated. maybe dependencies of the modules were not set correctly and drm is complied (and loaded) into kernel before agpgart-intel

[Martin-Éric Racine (q-funk)]

Actually, as of linux-image-2.6.31-11-generic version 2.6.31-11.38, even my initramfs-tools workaround doesn't work anymore.

Without having read the relevant kernel source, I'd still venture that one of the following causes might be our culprit:

1) the kernel doesn't offer management of module loading order dependencies (unlikely, but you never know).
2) the kernel offers management of module loading order dependencies, but KMS-related modules don't use it (unlikely, but you never know).
3) the kernel offers management of module loading order dependencies, KMS-related modules use it, but in an incorrect way.
4) the kernel offers management of module loading order dependencies, but it is broken, so all attempts by KMS-related modules to use it fail miserably.

Basically, we need a systematic method for loading modules and their dependencies in a predictable order, always. Right now, either we're lacking this or what we have doesn't work as intended.

[YannTech (yanntech)]

I have applied the #2 and I don't see again error :

[ 2.919077] [drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[ 2.919146] [drm:intelfb_restore] *ERROR* Failed to restore crtc configuration: -22
[ 2.919415] i915: probe of 0000:00:02.0 failed with error -22

But the issue is not solved, sometimes when I boot, my cpu still @ 100% on Xorg process :

  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 1396 root 20 0 451m 35m 7320 S 100 1.8 0:15.78 Xorg

I end my session and open again and my Xorg seem's to be OK

[exploder91 (d-cosner)]

I also applied the work around in #2 and the problem appears to be resolved. I should mention that I have Intel 8x on-board graphics and not the Intel 915 graphics outlined in the work around but the solution worked perfectly fine on my system.

Please fix this bug for Intel graphics, this is such a good release and I do not want to see anyone miss out on this one like the last release. Thank you Martin-Éric Racine for discovering the solution to this problem and sharing it here. Also, thank you to the community members that pointed me to this bug report.

[exploder91 (d-cosner)]

After a couple of re-boots it seems the problem has returned...

[Hadrien Mary (hadim)]

a temporary solution which have worked for me its too add x-swat ppa and update the system installing the new 2.9 intel driver :

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates && sudo apt-get update && sudo apt-get upgrade && reboot

Worked fine for me.... im not sure its the best to do because ppa are no supported by x-ubuntu team....if developpers thinks, its not the good way you can remove my comment.

Have fun guys

[mercutio22 (macabro22)]

I would like to note that twice, this bug surfaced after installing the file syncing application dropbox, which modifies nautilus and might be related somehow.

Fix #2 solved the issue.

My Asus 1005HA netbook (running under UNR 9.10 Beta+) is exhibiting what I believe is the same problem where about 3 boots out of 4 the video driver fails to initialize properly and then performs very slowly.

Linux agpgart interface v0.103

Oct 4 13:58:54 asmodeus kernel: [ 2.083826] i915: probe of 0000:00:02.0 failed with error -22

Except I don't get the "*ERROR* Cannot initialize the agpgart module." message the other users have.

I'm wondering if there's not some sort of race condition where sometimes the video hardware has settled down and is ready to be detected correctly and sometimes it has not.

I modified my /etc/default/grub file by commenting out "GRUB_HIDDEN_TIMEOUT=0" and setting "GRUB_TIMEOUT=3" to give the hardware time to "settle".

So far, this seems to be working.

[Scott James Remnant (Canonical) (canonical-scott)]

The AGP driver and DRM driver are loaded for entirely different devices, so there's no ordering requirement to enforce here. A simple fix would be for i915 to grow a depends on intel-agp.

[mercutio22 (macabro22)]

I take back what I said about the workaround. It stills happens randomly here.

[Scott James Remnant (Canonical) (canonical-scott)]

Try running the following:

  echo 'install i915 /sbin/modprobe -qb intel-agp ; /sbin/modprobe --ignore-install i915 $CMDLINE_OPTS' > /etc/modprobe.d/i915.conf
  update-initramfs -u

[Martin-Éric Racine (q-funk)]

Should this be bug renamed "i915 missing an explicit dependency on intel_agp" and filed upstream at kernel.org then?

@Scott ... comment #32 fixed it on my system.

[Scott James Remnant (Canonical) (canonical-scott)]

@Pete yeah that means we understand this bug, I should stress that if we roll with that fix for 9.10 then we should make sure we come up with a proper solution for 10.04

Proper solutions include soft dependencies between modules, or switching the AGP drivers to an agp subsystem

[YannTech (yanntech)]

#32 don't fix the problem (for me). At the first reboot I hope, but after few reboot the problem appear sometimes.

[Fabus (fabian-gebert-hh)]

I am also suffering from this bug. I'd like to help fixing it. But it is not possible for me to do a complete install.
If there is any way that I can help by using a Live CD, let me know.

[Bart Rose (jbrose3)]

Latest Grub update changed GRUB_TIMEOUT=10 in /etc/default/grub to GRUB_TIMEOUT="10". Removing double quotes and rebuilding grub solved problem for me.

[Tuukka Hastrup (tuukkah)]

As others have commented earlier, this bug appears to be somewhat random (a race condition?) and so a few successful boots don't mean the bug is fixed. If #32 doesn't do essentially more than #2, it fails every now and then at least here and as such I'm not surprised of comments #12, #31, #37.

I'm with #29 in this and would like to know if it's possible that the module load order doesn't matter as much as whether intel_agp has settled before i915 needs it. If so, could a work-around be udevadm settle or sleep 1 between the module loads? (Specifically, I'm now testing 'install i915 /sbin/modprobe -qb intel-agp ; sleep 1 ; /sbin/modprobe --ignore-install i915 $CMDLINE_OPTS' in /etc/modprobe.d/i915.conf, and at least it does no harm.)

[Cian Davis (davisc)]

#32 has worked for me for about 4 boots (previous record was 9/10 boots would fail to load). Will report if it fails.

This is a major problem for anyone with this chipset. The failure causes X.org to use 100% CPU - seems to be worst in Mozilla apps (Firefox and Thunderbird).

[Michael Lustfield (michaellustfield)]

I just wanted to throw out a Me Too. I'd like to mention that the only non-LUKS partition I have is /boot. So almost right away, I need to be entering my passkeys and these three lines show up right before that.

[drm: drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[drm: intelfb_restore] *ERROR* Failed to restore crct configuration: -22
DRM: Fill_in_dev failed.

[Fabus (fabian-gebert-hh)]

I am not quite sure if I am suffering from this bug or #431812 . All I can say is that it does not work out of the box (screen blanking just after the isolinux splash of the LiveCD) and that it does work when adding i915.modeset=0 to the boot args.
How can I tell what bug is the one that affects me?

[Anders Sjöström (anders-sjostrom)]

Fabus, try running "dmesg | grep drm" in a terminal window and see if you have lines like:
[ 3.159563] [drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[ 3.159608] [drm:intelfb_restore] *ERROR* Failed to restore crtc configuration: -22

[Mikko Rantalainen (mira)]

I'm also hitting this bug with yesterday's daily Karmic build on following hardware:
Motherboard: DG45ID with intel X4500HD [G45]

I've booted the system with this live CD three times and every time the results have been different:
1st boot: KMS did work and Compiz started but Xorg was taking 100% CPU time and everything was running extremely slowly - like everything were software rendered. I guessed at that time that the daily build had a broken intel driver and did not investigate further. The performance was too slow to be usable.

2nd boot: KMS did fail and I saw the *ERROR* messages above in the dmesg output. Compiz would not start. Terminal (VT1) did not work because the screen mode was incorrectly set.

3rd boot: KMS did work and Compiz started. Everything seems to work just fine. However, I'm seeing this in the dmesg output:
$ dmesg | grep drm

Workaround from #32 has so far after 12 reboots worked fine on my affected Dell Mini 10v netbooks with a "Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)". I'm running karmic beta with all latest updates.

[Rami Al-Rfou' (rmyeid)]

@32:
the workaround worked for me. Not sure, but I feel like compiz is not as snappy as it was before the bug occurrence.

[linuxcentre (linuxcentre)]

@49, in my case I am sure compiz is as fast a before because I was actually in the process of quantitatively testing frame rates in several apps before the bug appeared on my system and now that I put in #32 fix the rates are exactly the same. Testing was using Celestia, Stellarium, ExtremeTuxRacer, glxgears and a few more.

[Fabus (fabian-gebert-hh)]

@32: how can I test this with LiveCD?

[exploder91 (d-cosner)]

I read this when I asked about this issue today.

"One caveat. You need to disable KMS or else XVideo output will not initialize properly."

I have Intel G33 on-board graphics, this is a very common graphics card, thousands of people use these. This bug needs to be resolved, not worked around like in Jaunty. No other major distribution is suffering with this issue, so it is fair to say there is a permanent solution for this bug. There were enough issues with Intel graphics in Jaunty. Can we please make this bug a priority in Karmic?

[Emilio (turl)]

The 100% CPU Usage is because it fallbacks to software rasterizer, as glxinfo shows:

OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.6-devel

I will try with echo 'install i915 /sbin/modprobe -qb intel-agp ; /sbin/modprobe --ignore-install i915 $CMDLINE_OPTS' > /etc/modprobe.d/i915.conf
  update-initramfs -u

If the error occurs again, I'll tell you.

[Emilio (turl)]

Another thing, maybe this is related with Windows Vista? The two times I have experienced this, they were times after using Vista.

I will try booting Vista and then Karmic to see if Microsoft's OS is the culprit.

[Fabus (fabian-gebert-hh)]

I've now upgraded my Mac Mini 2nd gen system and it did not work. Then, I applied #32, but it still does not work:

Please let all of us know if this is resolved. Have you tried shutting down and bringing the system back up? That had triggered the bug every time for me. I am really hoping the kernel update has this resolved.

Provided your mirror has already got 2.6.31-12, just remove the patch #32 and upgrade:

sudo apt-get update

No improvement for me. 3 of 3 reboots the same since I "apt-get dist-upgrade" to get the new kernel that was held back. (And no, I never added the patch from #32).

Please let all of us know if this is resolved. Have you tried shutting down and bringing the system back up? That had triggered the bug every time for me. I am really hoping the kernel update has this resolved.

I did as you asked and did a complete shut down and started back up. So far, problem has not re-appeared. (now over 14 reboots)
I did not apply any patches fixes or upgrades before the kernel update.
Sorry for those of you still having the problem....

[Tim Gardner (timg-tpi)]

Here is a test kernel that attempts to force loading of the Intel AGP driver before i915 can proceed.

http://kernel.ubuntu.com/~rtg/2.6.3-12.39-module-depends

For example,

wget http://kernel.ubuntu.com/2.6.3-12.39-module-depends/linux-image-2.6.31-12-generic_2.6.31-12.39_amd64.deb
sudo dpkg -i linux-image-2.6.31-12-generic_2.6.31-12.39_amd64.deb

[exploder91 (d-cosner)]

Thanks R Lane, I appreciate you taking the time to try a shut down and posting your results.

[mercutio22 (macabro22)]

The bug hasn't manifested itself since I issued the command from comment #32 for a whole day now. (Thats around 17 boots in a row.

[Luís Silva (luis)]

Tim Gardner: the kernel you posted doesn't work for me... However, if I apply the fix from comment #32, I have kms again and the performance is back to normal.

[Boris Devouge (bdevouge)]

#63, you missed ~rtg/ dir in the second url. Thank very much, testing it now.

[Boris Devouge (bdevouge)]

on 2.6.31-12-generic #39:
5 reboots, 3 black screens after GDM login. When it works, its accelerated and fast, and displays this in the logs:

Trying #32 now.

[Cian Davis (davisc)]

Tim Gardner: Tried that new kernel. The problem recurred (and the kernel was slow to boot). Have a Dell D410 so used the i386 kernel. Cold rebooted 3 times, still no improvement.

#32 is still working for me (I did remove the modprobe.d conf before generating the initrd for the new kernel)

[Alessio Bolognino (themolok)]

I still have this problem and #32 doesn't seem to do anything. I would just boot, see a couple of lines then boot stops for few minutes , then resumes with fsck.

[Tim Gardner (timg-tpi)]

One more try: http://kernel.ubuntu.com/~rtg/2.6.31-12.39-MODULE-EXPORT

If this doesn't work for you, then please attach the output of dmesg as well as /lib/modules/`uname -r`/modules.dep for the failing kernel.

[Boris Devouge (bdevouge)]

This works for KMS here, however GDM and booting into gnome is slow, giving me an load average of 2.85 right after finishing to load gnome. in gnome glxinfo shows it is using hw rendering. and the desktop is snappy again. I cat'd the 2 files requested in one attachment.

[Martin Pitt (pitti)]

I can reproduce this pretty reliably on my Latitude D430 when booting with the internal screen and undocked. Curiously I (almost) never get this effect when booting docked and with the external screen; I guess some slight timing difference just wins/loses the race there.

I tried both of Tim's test kernels, and I still get the issue. The final -12.40 upload isn't built yet, so I could not test this one yet.

[Martin Pitt (pitti)]

dmesg when it fails:

So it still loads drm first, then i915, then agpgart.

Hmm. Isn't the actual problem that agp is loaded before drm? Adding a
dependency to i915 wouldn't fix that?

> grep i915 /lib/modules/2.6.31-12-generic/modules.dep

$ grep i915 /lib/modules/2.6.31-12-generic/modules.dep

"grep agp" still yields no dependencies.

This is with -12.40 now.

@Martin: Actually, I was proceeding on the assumption that intel-agp needed to be loaded before i915. Still, its curious that you don't have the i915 dependent on intel-agp. I'll do some more digging.

[Falco (xfalcox)]

Sometimes I got:
[ 4.118453] [drm:drm_fill_in_dev] *ERROR* Cannot initialize the agpgart module.
[ 4.118521] [drm:intelfb_restore] *ERROR* Failed to restore crtc configuration: -22

I'm on eeepc 1000ha with Ubuntu 9.10 Beta @ 2.6.31-11.

It's pretty random, and no fix till now.

This is probably also required, but not sufficient (it _also_ needs to
come before drm).

Thanks a lot for your efforts!

[Kels (echukwuogor)]

The fix from #2 worked for me. About 10 restarts/boots without incident. Yet to try the 2.6.31-12 update

[Kels (echukwuogor)]

GM965, x3100 graphics, x-swat drivers (~2.9.0)

[Kels (echukwuogor)]

Sorry, that's xorg-edgers.

[Kels (echukwuogor)]

2.6.31-12 is just fine. (With fix from #2)

[Jerone Young (jerone)]

Have an Inspiron 15n that has a:

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)

Trying the fix in comment #71 DOES NOT fix the issue. It will still fail at times.

This is what I did to produce the problem.
Running on Battery power:
1) Boot from cold boot (works)
2) Restart ... KMS fails on boot .. you notice the Ubuntu logo is fuzzy (meanig not at LCD native res) .. also X is slow
3) Restart .... KMS fails .. blah blah
4) Restart ... KMS fails .. blah blah

Looks like if you run off battery you can get one good boot then restart and fails every time. This is how I can accurately reproduce the issue.

I see this from the kernel messages when it fails:

[Tim Gardner (timg-tpi)]

@Martin - I think I've figured it out. The MODULE_IMPORT/MODULE_EXPORT macros didn't work for amd64. I guess the compiler is smart enough to detect unused symbols. I've applied a big hammer to the problem, so it should be fixed in the next upload.

As for drm dependencies, i915 is already dependent on the main drm module.

Ah! Indeed I am using amd64 here.

Awesome, thanks!

So your current upload introduces the drm -> intel_agpgart dependency?
Out of curiosity, what happens on platforms where intel_agpgart
isn't needed, but drm is?

Thanks, Martin

[Tim Gardner (timg-tpi)]

@Martin - this is a generic problem with a number of the drm/agp hardware pairs as long as the AGP hardware code is built as a module. Its also worth noting that this load race issue affects network drivers that are consumers of libphy, e.g., if the associated MII driver has not already registered with libphy, then the NIC driver can't do much. I solved that issue awhile ago by building into the kernel all of the phylib HW modules, not the most elegant solution. I'm going to talk to upstream to see if there is a better solution.

@Daniel - you appear to have a different problem, i.e., its no longer module load order. Start a new bug using the information at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies so that all of the relevant information is attached, e.g., 'ubuntu-bug -p linux'.

[crashsystems (crashsystems)]

The updates fix this bug on my system. However, when I log in now, compiz is
not running. I have to run compiz --replace to get it running, but it works
just fine once I do that. Would this be related to this bug, or should I
file a new one?

[Tim Gardner (timg-tpi)]

@crashsystems - yes, you have a different bug.

[Pete Graner (pgraner)]

@crashsystems most likey its not a bug. gconf remembers your last setting with was without compiz.

Go to System->Preferences->Appearance->Visual Effects

and select either Normal or Extra and compiz should come up and stay.

I was still experiencing this today despite having the later kernel installed, because for some reason grub2's menu was not showing all of the installed kernels but rather was stuck on -11. When I manually change the grub commands to boot -15, the problem seems to be fixed.

OK, my comment in #112 was a local problem because I hadn't completed the grub2 upgrade - but if others are still seeing this bug they might want to check grub's actually booting what they think it should be.
