Title:
  Direct firmware load for radeon/kaveri_sdma1.bin failed with error -2

Bug description:
  == SRU Justification ==

  Impact: CONFIG_DRM_AMDGPU_CIK enables experimental support for some
  AMD hardware in the amdgpu driver. It's not considered stable yet and
  is not working properly with some hardware.

  Fix: Disable this option. The hardware which is no longer supported by
  amdgpu is all supported by the radeon driver.

  Regression Potential: It's possible that some regressions might be
  seen by users with affected hardware, but generally using radeon for
  this hardware should be more stable.

  ---

  Version 1.149 of the package does not have
  /lib/firmware/radeon/kaveri_sdma1.bin needed for the latest AMD DRM
  module.

  After booting my monitor is blank.

  For other AMD chipsets *_sdma1.bin is needed as well:
  drivers/gpu/drm/amd/amdgpu/cik_sdma.c(126): snprintf(fw_name, sizeof(fw_name), "radeon/%s_sdma1.bin", chip_name);

  Similar to https://bugs.launchpad.net/ubuntu/+source/linux-
  firmware/+bug/1183777, https://bugs.launchpad.net/ubuntu/+source
  /linux-firmware/+bug/1218691

  Timothy
