Ok, I've cloned the ubuntu-trusty repo, used git bisect and found the
culprit:

dc9c3ed611922e769b1fd595f8f99a93d69c026d is the first bad commit

    x86/efi: Runtime services virtual mapping
    
    BugLink: http://bugs.launchpad.net/bugs/1297658
    
    We map the EFI regions needed for runtime services non-contiguously,
    with preserved alignment on virtual addresses starting from -4G down
    for a total max space of 64G. This way, we provide for stable runtime
    services addresses across kernels so that a kexec'd kernel can still use
    them.
    
    Thus, they're mapped in a separate pagetable so that we don't pollute
    the kernel namespace.
    
    Add an efi= kernel command line parameter for passing miscellaneous
    options and chicken bits from the command line.
    
    While at it, add a chicken bit called "efi=old_map" which can be used as
    a fallback to the old runtime services mapping method in case there's
    some b0rkage with a particular EFI implementation (haha, it is hard to
    hold up the sarcasm here...).
    
    Also, add the UEFI RT VA space to Documentation/x86/x86_64/mm.txt.

Title:
  System does not boot

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I'm currently stuck with the 3.13.0-19-generic version.
  With both 3.13.0-20 and 3.13.0-21, the boot process fails very early: even without "quiet splash" in the kernel command line, I do not get any message beyond those of EFI GRUB (loading kernel & initrd).
