Ubuntu Studio does not boot in Hyper-V Generation 2 VM

Bug Description

Using the Ubuntu Studio 14.04 release image (64bit), it is impossible to boot or install in a Hyper-V generation 2 VM.

Using either option in Grub (install/live system) results in the attached error screen after the animated Ubuntu Studio boot logo (plymoth),

It should be noted that I use the same settings with Xubuntu, where it works and never showed this problems.
Additionally I noticed that it is not possible to interrupt plymoth to see the kernel log output, it seems the Hyper-V keyboard module is not loaded.

As the bug happens during boot before console access is possible or any other applications are loaded, I report this bug against the linux package. Feel free to reassign it to another package if needed.

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

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'.

I tested the daily image from May 5th of Ubuntu Studio. It shows the same error like the trusty release image.

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.
