Lars Peter Thomsen, thank you for reporting this and helping make Ubuntu
better.

In order to allow additional upstream developers to examine the issue, at your 
earliest convenience, could you please test the latest upstream kernel 
available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please 
keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the 
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was 
released upstream.
4) Install instructions are available at 
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this issue is fixed in the mainline kernel, please 
add the following tags by clicking on the yellow circle with a black pencil 
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your help.
