This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

Are there any other issues with the system, or just this message?

[Cristian Aravena Romero (caravena)]

just this message. Scares

[Juan Pablo (jopojuan)]

I got the same message on startup, but I don't think it's a bug. Just it's annoying message on startup

[ldmpub (ldmpub)]

The same INFO message for me: I have the message each time at startup just before Ubuntu splash screen.

[MorrisseyJ (morrissey-james1)]

I get this message, but my system is also experiencing random freezes. Bug detailed here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1174275

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Ari (ari-lp)]

This shows up for me as well shortly before lightdm starts. Following the advice in [this bug report](https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1095751) I installed the Saucy version of the bcwml driver in order to be able to use WLAN on my system.

I do not agree that it is Invalid, neither Expired (in real world..).
I use LTS ubuntu version which support should keep going few years..

And the message is realy annoying.
 Why we do have various slashscreens and pictures even background behing Grub menu, when such a void message switches everything off and displays useless text message each boot...

In addition to that, cfg80211 keep filling logfile by waste majority of void messages about Wifi frequencies and regullatory.
Perhap afte DEBUG mode is turned on, this everything would be perfect. And for source code creator..
But as for everyday use when everything runs perfect, this is just annoying bothering behavior.

Thank You for reading.

[ekerazha (ekerazha)]

This "Info" message should be hidden. Having a console message before the boot screen is ugly, moreover it does confuse non-technical users: have you ever seen a cryptic kernel message before the Microsoft Windows boot screen? I replaced Windows XP with Ubuntu 14.04 on a netbook and its owner immediately asked "what is this message??!".

[Klavs Anson (klavsanson)]

I found a possible workaround for this problem - running: "echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash" and after that "update-initramfs -u" fixes problem.

[bluegeek (bluegeek)]

Thanks, this workaround works for me (Ubuntu 14.04). Any idea about why this works? any possible side effects?

[Doctor Jellyface (doctorjellyface)]

I confirm that the workaround proposed at #14 works (thanks!). Lubuntu 14.04.1 64 bit.

No side effects yet, but it makes the boot a lot nicer, the plymouth loading screen with the Lubuntu logo now shows through the whole boot time. Before the workaround there was a black screen for 15+ seconds, then the error showed, and then the loading screen, which was there for about 3 seconds. Now the loading screen is there the whole time. If you look at it this way, it's a quite important graphical glitch.

(if anyone's wondering at the loading times, Wubi here)

[Markcortbass (markcortbass)]

I agree that this bug should be fixed with the given workaround.
It does not have a negative impact on the installation.

[Damir Butmir (d4m1r2)]

That workaround (comment #14) does NOT work for me. It successfully returns "FRAMEBUFFER=y" in the terminal but doesn't actually correct the problem.

I am seeing this message 100% of the time on boot, however in my case it is a little different....I am running a dual monitor setup and on my primary monitor I see the expected LightDM login screen. I used to see the exact same screen on my external secondary monitor as well up until a recent slew of updates. Now on my secondary screen it just shows a purple background with this cfg80211 etc text on it....

Issue appears on fresh install of 14.04.1.

$ uname -a
Linux PS001 3.13.0-39-generic #66-Ubuntu SMP Tue Oct 28 13:30:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty

I did not have this issue on a previous install of 14.04.1 x64 on the same machine, using legacy boot and primary ext4 / partition without a separate /boot partition.

I updated my system to EFI and LVM, using a spearate vfat /efi partition with / on a logical volume, and now I see this message at each boot up.
