** Description changed:

+ == 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-
