system will not start after updating to kernel 3.5.0-27

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

The described issue occurs with the 3.5.0-27 kernel on my machine. Booting 3.5.0-26 does not show this behavior.

Same for me...
Installing/Building process to /boot folder for the 3.5.0-27 kernel on my machine took a extremly long time (compared to earlier issues).

i am running kubuntu 12.10 with the backports ppa.

today, i ran an update, which included 3.5.0.27.43. i had an issue with the install being only incomplete because apparently i had not enough room in my boot partition. after deleting old images, the -27 kernel installed automatically. after trying to boot into it, i found I could not log in (kept throwing me back to login screen after going blank and flashing something too fast to read). I had to remove the current kernel and re-install kubunut-desktop in order to log in. Things appeared to be ok, so i tried installing -27 again. (sudo apt-get install linux-image 3.5.0-27-generic).

after reboot, many things were not working: external monitor, keyboard/mouse, wifi and ethernet, etc. Lappy resolution was way small too. Removed -27.

-26 seems to be working...

hmm...

With standard settings, system doesn't boot. It stops booting somewhere around framebuffer initialization.

When booting with nomodeset the system boots but X cannot initialize the radeon driver and starts with VESA driver.

I have two graphics cards:
Radeon HD 3300
Radeon HD 4650

Booting with 3.5.0.26 works fine.

Xubuntu 12.10
Upgraded today (2013-04-09).
New kernel will hang with a blank screen.
Ran the same kernel in recovery mode: got a dmesg log.
Running the previous 3.5.0-26 works.
It looks like the i915 driver crashes, but I can not be sure.

Host is a Lenovo T530.

Same problem on a second computer (Notebook Sony Vaio VPCZ1).

Distribution is Ubuntu 12.10 (forgot to mention in previous comment for my other computer).

Work-around for Lenovo T530:

The host has dual video adapters: an Intel integrated low-power and an NVidia discrete high-performance.
The host has a special (AFAIK Windows-Only) mode with both video adapters running (one one stand-by) to be toggled by the OS. The mode is called 'NVidia Optimus' in the BIOS settings.
With 'NVidia Optimus' the kernel crashes (or blanks-out).
With 'Integrated' the kernel boots (and chooses i915 driver).
With 'Discrete' the kernel boots (and chooses whatever nouveau/nv/nvidia is available).

So for the work-around: choose to use the Discrete OR the Integrated video adapter.

Same problem Ubuntu 12.10 (64 bit) on HP-envy pavillon

 ok with Kernel Version: 3.5.0-26-generic

well, it seems for me my issue may have just been things didn't configure properly after clearing out old kernels. i should not have tried to install the new version of kernel directly. installing the kernel meta-packages and the kubuntu desktop meta-package seems to have fixed it. (don't know if the desktop one was necessary, but i don't think it would hurt...):

sudo apt-get install linux-generic linux-headers-generic linux-image-generic kubuntu-desktop

this would pick up the latest available kernel image version packages.

if you run regular ubuntu, i believe the meta is ubuntu-desktop instead.

hope that helps someone.

sorry ... first time I use this bug reporting ... my apologize

Regarding the comment of poikiloid:

At my two computers wrong/missing packages don't seem to be the problem. The following command line reports that all packages are at the newest version.

sudo apt-get install linux-generic linux-headers-generic linux-image-generic ubuntu-desktop

But probably there is a problem with more than one graphics card. My desktop has to PCIe graphics cards. My notebook has two switchable graphics adapters.

Same problem here on lenovo laptop W520: 3.5.0-27 hangs on boot, 3.5.0-26 boots fine. Packages are all updated.

Hi!

After installing the on-line update April 10, I can't start Ubuntu 12.10 on Linux 3.5.0-27. The 3.5.0-26 kernel seems to run as usaual.

I think this problem is caused by dual graphics configuration – most likely of different types.
I reported the bug for a A6-3650 in combination with an Nvidia FX6200
The same issue was present on my system up to kernel 3.5.0-17 when it disappeared and now reappeared with 3.5.0-27.46.
Also I noticed that with kernel 3.5.0-27.47 issue occurs every second boot.

Hope this helps someone to fix this bug once and forever

Hii!

What kind of activity is ongoing to replace the faulty upgrade package for Ubuntu 12.10/3.5.0-27 with the "blank screen behavior"?

I am running Ubuntu 12.10 on Intel Core 2 Duo CPU P9700 2*2.80 GHz with Intel GM 45 Express Chipset.

This bug also affected me.
Last working kernel was 3.5.0-26.
Starting from 3.5.0-27 and 3.5.0-28 system booting with the black screen.
Workaround is to add 'nomodeset' boot option, but the screen resolution in Gnome will not proportional.

Same problem. The default 12.10 install with 3.5.0-17-generic boots fine, but the latest kernel/initrd 3.5.0.27-generic gets me into a black screen on boot, I do not even see the ubuntu splash screen after grub.

This is a HP Pavilion dv7 laptop with Intel switchable graphics. On windows 8 this computer has similar problems as soon as the ATI graphics drivers get installed. I supposed that this is something similar.

Hi!

Maybe my foundings can help!

I had a Ubuntu 12.10/3.5.0-27 with the "blank screen behavior".
I am running Ubuntu 12.10 on Intel Core 2 Duo CPU P9700 2*2.80 GHz with Intel GM 45 Express Chipset.

I upgraded to Ubuntu 13.04 (it took a couple of hours, anyone else experienced that?) but the same black screen problem!

I found this link http://ubuntu-tutorials.com/2010/05/06/ubuntu-10-04-lucid-blank-screen-at-startup-workaround/
from 2010 !!

And there I found the solution at least for me having a nVidia graphic Card. The steps are:
1) Edit "/etc/default/grub" as administrator
2) Update this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
 with the option "nomodeset" for nVidia

Enter a similar hardware specification for other graphic cards.

3) Run "update-grub" as administrator

I am back on track again!!!
