Bug Description

SRU Justification

Impact:

After upgrading to linux 3.5.0.27.43 my notebook does not boot. Loading recovery version of same linux kernel stops somewhere in the middle and does not even show a console.

Previous version of linux 3.5.0.26 works just fine.

Testing:

Boot a kernel with the relevant patch applied and you should get to a login screen/prompt.

NOTE the linux version reported with apport (3.5.0.26) is last working one not the subject of this bug.

Can you follow the "Boot options" instructions on the following wiki to enable additional output on boot:

https://wiki.ubuntu.com/DebuggingKernelBoot

As mentioned on the wiki, it would be great if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand.

The wiki page does not (seem to) correspond to this version of grub. A short explanation of how to log boot output to a text file would be helpful. I did remove the quiet and splash options but the other options are different.

Starting with Natty (Ubuntu 11.04), also remove the parameter vt.handoff=7, and on the line that reads set gfxpayload=$linux_gfx_mode, replace with set gfxpayload=text

Does not correspond to what I see. I have a parameter $vt_handoff (that I removed) but no gxfpayload line.
I am going to try the updated kernel suggested. Fingers crossed.

The latest 3.5 stable kernel got to the login screen but in an incorrect graphics mode and without the mouse or keyboard functioning. I noticed that the Ethernet was connected but the router showed that it was at the low (10mB) speed.

I only upgraded the kernel. I did not upgrade the headers - Is it necessary?

I a currently booted into a kernel that is version 16 from a few weeks ago. Everything is functioning normally with this kernel.

Let me know what to do next and how to assist in debugging. I am not a Linux admin but I am a programmer so I can at least follow instructions :-)

I have the same problem... Lenovo ThinkPad T530 that has been running Linux (pretty much any distro) fine until recently. Currently dual-booting Win7 Pro and Ubuntu 12.10. Tried installing Fedora 18 and Fuduntu 2013.1 for multi-boot about a week ago. Live USB worked fine... install went fine... initial boot went fine... downloaded all the necessary updates and rebooted... got the same blank black screen after grub as described here. Given the number of updates applied at the time (hundreds) I literally had no idea where to even look, and just went back to Ubuntu 12.10 as it was still working fine.

Until the last update involving kernel 3.5.0-27. Rebooted... same blank black screen after grub.

Selected the 'Advanced Options' -> 3.5.0-26 generic kernel, and was able to boot normally (like now). When I tried the 3.5.0-27 failsafe kernel, I get partways through the boot cycle but it just hangs at pretty much the exact same point every time.

I'd like to help... but it seems that there is no good way to capture the boot messages when the machine doesn't even make it all the way through to a console? Short of writing down by hand the last few messages displayed on the screen when the machine locks up, and re-posting them here, what can I / we do to help? I mean, I'll do that if thats the only option, but I was hoping there was something else.

Just a thought... given that the three distros mentioned have very different kernel versions (I was told F18 was at something like 3.8.5-201?) it seems that its some small security update that would be common between the different distros that would cause all to recently not boot on certain hardware...?

Also just experienced this on a desktop.

Just installed a bunch of updates, one of which was:
linux-headers-generic:amd64 (3.5.0.26.32, 3.5.0.27.43)

Since the system boots fine into 3.5.0.26, it stands to reason it must be this.
In a duplicate bug report, lots of people reported they have this issue on machines with older Radeon graphics cards,
specifically:

Radeon HD 3000 Series
Radeon HD 4000 Series

From reading the comments here, it seems like the bug also affects systems with other hardware.

Mine falls into the latter category. Off course, I'm running the noveau driver on that, since these HD cards don't support the newer xorg server versions, while noveau's good enough for my purposes not to downgrade.

Could somebody with this problem try to boot into 3.5.0.27 in recovery mode, I know it gets halfway there -- perhaps someone could pull up a root console after issuing a Ctrl-Alt-Del signal when it decides to stop booting? (I apologize, I'm in a bit of a time bind right now.)

I think it would be helpful to see what the "dmesg" command would say about the boot messages, if indeed it would work.

I have a radeon HD 4670 display.

While in grub I edited the boot line to include "radeon.modeset=0". This allowed the
system to boot without problems, although the graphical response was very slow.

So I think the problem is due to changes in the radeon driver KMS code.

Re: comment 21 by Luis Henriques (henrix)

I have a Radeon HD 4670 frame buffer.

I installed all your amd64 debian files. There was no change.

I noticed that the network card never initialized itself (the light on my router never changed from yellow to green). The keyboard had enough functionality so that the NumLock light would respond to pressing that key. I still could not catch the last contents of the console window.

 Again if I added "radeon.modeset=0" to the boot, things worked with a much slower display.

However, the computer also has a Intel Core i5-2400 Sandy Bridge processor, which comes with a built-in Intel HD Graphics 2000 GPU. That GPU is not active, as in - only the graphics card is being used by a single screen.

I am posting this for anyone testing kernels that has as weak an understanding of Linux as I do :-)

The next to last set of kernels did not show up in my Software Center so I ran the following commands in the terminal.

sudo dpkg --get-selections | grep linux

That showed me a list of stuff installed with linux in its name which means the kernels I have been installing

Then I ran

sudo dpkg -r linux-image-extra-3.5.0-28-generic
sudo dpkg -r linux-image-extra-3.5.0-28-generic
sudo dpkg -r linux-image-3.5.0-28-generic

Since those are the kernel packages I installed. And now on to the last set posted. If I forgot anything feel free to comment.

Would you say it's safe to try and upgrade to Raring now, or is the fix still in the works there?
