Bug Description

I'm getting a kernel panic when I try to boot the latest daily image. It did work a couple of days ago(can't remember exact date, but I would guess 9th or 10th of March). I've tried booting it as UEFI and legacy mode, with the same result. I attached an image of the error.

This is the 64-bit daily image of ubuntu 14.04 (trusty-desktop-amd64.iso )

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.

Also, do you have a prior version of Ubuntu on the system that boots? If so, can you install the 3.13.16.36 kernel and see if it also has the issue? It can be downloaded from:
https://launchpad.net/ubuntu/+source/linux/3.13.0-16.36/+build/5659610

If 3.13.0-16.36 does in fact boot, can you then try 3.13.0-17.37 and confirm it does not boot? It can be downloaded from:
https://launchpad.net/ubuntu/+source/linux/3.13.0-17.37/+build/5800060

For both these kernels, you need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

I've attached a picture of the log as described in the link you gave me.

Regarding installing the newer kernel on my installed system: It should be easily reversible if it doesn't work, right? As I use this computer daily, I don't want to break my current install. Ubuntu 12.04 was pre-installed by DELL if that matters

Yes, you can always boot a prior kernel, but selecting it from the GRUB menu. Hold down (right) SHIFT to display the GRUB menu during boot. In certain cases, pressing the ESC key may also display the menu.

I was able to start both kernels with 12.04. I could also start todays daily image (20140318) from a live-usb. So I guess it's resolved for now. I'll check out images reguraly until release in case it would break again.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

  With the recent release of this Ubuntu release, would like to confirm if this bug is still present. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

Changed in linux (Ubuntu):
status: Confirmed → Incomplete
tags: added: kernel-request-3.13.0-24.46
