Bug description:
  When using the fglrx driver gpu-manager will fallback to UXA. UXA is
  not implemented for broadwell in the 910 driver, but is required when
  using fglrx for offloading. When using FGLRX in the IGPU (integrated
  gpu) mode fglrx unloads itself and makes intel drive the screen. This
  crashes with SNA, because fglrx steals the driver privates.

  Upstream has some commits to fix this, but they're missing in the 910
  driver from trusty.
