Title:
  Ubuntu 16.04 won't properly boot due to radeon module issue

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When I boot an Ubuntu 16.04 live DVD on a Gateway system with an AMD
  A6-5400K APU, with an integrated Radeon HD 7540D graphics adapter, I
  get a black screen with no video image.  If I boot the live CD with
  "nomodeset" added to the kernel parameters, the system boots and shows
  the desktop at low resolution.  If I look at "dmesg" output, I see
  these messages:

  ubuntu@ubuntu:~$ dmesg | grep "UMS"
  [    4.827258] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!
  [   39.561534] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!
  [   76.905778] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!
  ubuntu@ubuntu:~$ 

  We currently run Ubuntu 14.04.2 on the system with no issue, including
  using the "radeon" video driver.
