Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1392071

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

apport-collect 1392071 ends with HTTP 1.1 403 Forbidden

[penalvch (penalvch)]

Dirk Roos, could you please try the apport-collect again?

[Dirk Roos (bitborne)]

aport-collect still ends with ends with HTTP 1.1 403 Forbidden as soon as i select "Allow ubuntu-server to access my Launchpad account".

Note: this is done in terminal on a ubuntu server installation

Authorize application to access Launchpad on your behalf

Confirm Computer Access

   The Ubuntu computer called ubuntu-server wants access to your Launchpad account. If you allow this, every
   application running on ubuntu-server will have read-write access to your Launchpad account, including to your
   private data.

   If you're using a public computer, if ubuntu-server is not the computer you're using right now, or if something
   just doesn't feel right about this situation, you should choose "Do Not Allow 'ubuntu-server' to Access my
   Launchpad Account", or close this window now. You can always try again later.

   Even if you decide to give ubuntu-server access to your Launchpad account, you can change your mind later.

   Allow ubuntu-server to access my Launchpad account:

   Until I Disable It For One Hour For One Day For One Week

   or

   Do Not Allow "ubuntu-server" to Access my Launchpad Account.

Dirk Roos, thanks for the additional information. Could you please boot into the live envionment and then perform the apport-collect via http://cdimage.ubuntu.com/daily-live/current/ ?
