Bug Description

CPU: Intel
GPU: NVidia

Summary:
The following error flashes onscreen during boot, while the system is still in text mode (plymouth):
intel ips 0000:00:1f.6: failed to get i915 symbols, graphics turbo disabled

It's onscreen for several seconds during first boot, while we set up the home partition. The error is shown onscreen during subsequent boots too, though for less than a second. The error is also present in dmesg.

I've see the error in dmesg with both the nouveau and nvidia drivers, but it only appears onscreen during boot with the NVidia drivers (presumably because plymouth is in text mode).

Setting priority to 'High' since the error is onscreen during first boot.

Can you please test the kernel under http://kernel.ubuntu.com/~manjo/maverick/lp651104/ on a T510 (434926U) and report back here. It has the fix to enable intel graphics turbo which is supposed to take care of the message we are seeing.

I tried your kernel, Manoj, but it didn't fix the problem for me on an HP Elitebook 8740w (see bug report 725135). Thanks, though.

Andy Whitcroft (apw) wrote :

I am somewhat confused. The message in question is emmitted at KERN_ERR, which should be automatically suppressed during boot when 'quiet' is in effect? Do you have a picture of this being displayed, I am trying to work out if plymouth is transcribing this, or it is a raw output from the kernel.

There is a very long Ubuntu forums thread about this issue here: http://ubuntuforums.org/showthread.php?t=1594981

One user suggested a workaround: http://ubuntuforums.org/showpost.php?p=10502147&postcount=94
echo "softdep intel_ips pre: i915" > /etc/modprobe.d/intel-ips-dep-i915.conf

There is also discussion of a patch: http://ubuntuforums.org/showpost.php?p=10467296&postcount=77
Notably, that patch http://lists.freedesktop.org/archives/intel-gfx/2010-December/009017.html has already been applied upstream to the Linux kernel in 2.6.36.3: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.36.y.git;a=commit;h=63ee41d794d9c555f84205517a68509848988760

FYI - The "softdep" workaround did not work on my system (Dell E6410 with Nvidia graphics) using linux-image-2.6.38-4-generic from http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu/

Robert Hooker (sarvatt) wrote :

It's raw output from the kernel before plymouth is even loaded. downgrading it from dev_err to dev_info suppresses it as well.

http://sarvatt.com/downloads/patches/0001-intel-ips-demote-graphics-turbo-error-to-dev_info-to.patch

The problem in this bug is that the error is emitted even if i915 isn't used at all and it stays on the screen during a text mode plymouth boot. the patch in manjo's kernel just makes it attempt relinking to i915 again for the people getting the error that are actually using intel graphics, and the actual error still shows up at the beginning too with it.

Hi!
The issue is there for me as well on my Lenovo W510, Nvidia Quadro FX 880M and 64bit 10.10. (Kernel: 2.6.35-27-generic)
I tried this workaround ( http://ubuntuforums.org/showpost.php?p=10502147&postcount=94 ) but that didn't help.

From the long Ubuntuforums thread: (http://ubuntuforums.org/showpost.php?p=10613484&postcount=115). Running the 64-bit kernel from http://duopetalflower.blogspot.com/2011/03/custom-kernel-26381-ubuntu-amd64.html seems to have fixed the problem for me.

Perhaps it can be of use?

I'm running 12.04 (32bit) w/ kernel 3.2.0-24-generic-pae on a Dell E6510 with NVIDIA Corporation GT218 [NVS 3100M] (rev a2) and I'm hitting this bug. I've blacklisted the intel_ips module (as per comment #15) and the laptop is now booting properly. Before putting this in it seemed to be a crap-shoot as to when the system would come up...

Status changed to 'Confirmed' because the bug affects multiple users.

Manoj Iyer, 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) 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-v3.13-rc5

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.
