[quantal] Unable to boot into 3.5.0-17 kernel

Bug Description

After upgrading to the latest kernel version, I am unable to boot, and receive just a blank screen. Removing the 'quiet splash $vt_handoff' options (but keeping nomodeset, which I normally use), I get a flashing cursor, but nothing else. I can boot into recovery mode and press 'resume boot', but X does not load.

(I reported this bug from 3.5.0-15, so some of the apport information could possibly be wrong)

Does this issue also happen in the 3.5.0-16 kernel?

Same problem on my DELL Latitude E6520

I can't tell, as I jumped straight from 0-15 to 0-17, and 0-16 isn't available from apt-get. Is there another way to install the 0-16 kernel from the repositories?

and same problem with a live-usb daily quantal

but it works fine with another machine

Can you test the following two upstream kernels? We can perform a kernel bisect if 3.5.4 does not have the bug, and 3.5.5 does:

v3.5.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.4-quantal/
v3.5.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.5-quantal/

Both of those boot fine, although other errors (USB/Wifi) are envountered. Versions tested:

Can you also test the 3.5.0-16 kernel, which can be downloaded from:

3.5.0-16.24 boots fine, but has the same problem with USB devices not working. Should I raise a separate bug about that, or do you think the two are related?

Joseph Salisbury (jsalisbury) wrote :

Just to confirm, can you boot back into v3.5.0-17 and confirm the bug is back. If it is, this issue would be due to an Ubuntu specific change in 3.5.0-17 since the 3.5.4 and 3.5.5 upstream kernels boot fine.

If the bug comes back in 3.5.0-17, I can perform a kernel bisect between 3.5.0-16 and 3.5.0-17.

It doesn't work for me with 3.5.0-16 ; 3.5.4 ; 3.5.5

Attempting to boot the 3.5.0-17.28 kernel (with the extras package installed) is no longer giving me a blank screen, but is still appearing to freeze after 'Loading initial ramdisk' is displayed.

When I switch on my wifi button, Quantal boots with fine with 3.5.0-17 !

*switch on my wifi with the hardware button

Now, with wifi activated, i can boot on 3.5.5 kernel and 3.5.4

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


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.

I've had a fiddle with the boot options, and it looks like it's actually booting OK (the text-based login screen briefly appears). I'm guessing the problem then is actually with starting the xserver, which for some reason irrevocably blanks the screen.

@penalvch : OK, it's here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1074349
It's the same problem

Joel Cross (ukch) wrote :

@Joseph any update on this bug? Do you think it will be safe for me to upgrade to Raring, or should I stay on Quantal for now?

Joseph Salisbury (jsalisbury) wrote :

One option would be to boot Raring from a Live CD on your system. That will tell you if everything works ok before upgrading.

Joel Cross, could you please provide the full computer model as noted on the sticker?

HP Pavilion g6. Other than that I don't know, as there is no sticker or anything.

Joel Cross, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:

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.
