Successful stderr of `dmesg` on L0 with Kernel 3.14.0-0.rc1.git4.1.fc21.x86_64

I just tested with this Kernel 3.14.0-0.rc1.git4.1.fc21.x86_64 my bare-metal,
booted L1 (running: 3.14.0-0.rc1.git4.1.fc21.x86_64) and L2 ( running
3.11.10-301.fc20.x86_64')

Couple of observations
----------------------

  - I don't see the soft lockups any more on host
  - L2 is just stuck on:

      Booting `Fedora, with Linux 3.11.10-301.fc20.x86_64'

    when booted over a serial console. I tried booting into single 
    level, it's just stuck there, attempting to "Booting a command list"

  - To isolate the problem Kernel, I also tried:
      - Shutdown L2; Booting L1 into 3.14.0-0.rc1.git1.1.fc21.x86_64;
        Start L2 with 3.11.10-301.fc20.x86_64 -- stuck on boot.

        Repeated the above test with booting L1 into 
        3.12.8-300.fc20.x86_64, and starting L2 results -- stuck on
        boot.

    So, from the above symptoms, I'm inferring the problem appears to be 
    with current L0 Kernel (3.14.0-0.rc1.git4.1). Because
    booting it into its older Kernel (kernel-3.12.8-300.fc20.x86_64),
    brings up L2 successfully

I'm yet to investigate further here.
