  [Trusty] Switching framebuffers fails on VMs using cirrus

Status in “linux” package in Ubuntu:

Bug description:
  Trusty Server (daily image 2014-01-15)
  Kernel: 3.13.0-3.18-generic 64bit

  Booting a VM which is set to use cirrus graphics there seems to
  (still) be a problem with the framebuffers. The kernel has a special
  KMS module which also has a framebuffer interface. During boot
  plymouth likely keeps the fb open which the kernel tries to replace
  the generic FB with the special one (and fails). Symptom is a system
  which seems to hang on boot when looking at the graphical console.
