@Martin Suc - You actually have a different (albeit related) bug.  This
bug is about the radeon module.  Your bug is abou the amdgpu module,
which is the driver to support the Radeon R9 285 "Tonga" and all future
GPUs, including Carrizo APUs and the to-be-supported Fiji/Fury GPUs.
This AMDGPU driver will live alongside the current "Radeon" DRM driver
as the kernel components to AMD's open-source Linux driver offering.

The amdgpu module and it's associated firmware is optional for the GPUs
listed in comment #11.

  warning messages I saw when I upgraded to 3.11.0-3-generic

  Further digging found bug 1183777

  As mentioned in that bug, I did contact the named person:

  "Hi,

  I'm still seeing the errors for
  KAVERI firmwares
  being missing in the latest kernel :
  phillw@piglet:~$ uname -a
  Linux piglet 3.11.0-3-generic #8-Ubuntu SMP Fri Aug 23 16:49:15 UTC 2013
  x86_64 x86_64 x86_64 GNU/Linux
  As the 1st Beta is creeping up fast, do you need this raising as a new
  bug?
  Regards,
  Phill."

  The reply is:

  "As far as I can tell, the KAVERI firmware (and hardware) is not
  publicly available yet, so that's not a bug with the linux-firmware
  package. If you want to file a new bug about the warning messages,
  please file it against the linux (kernel) package. Until the firmware
  is available, I'm not really sure what the fix for that would be,
  other than removing/commenting out the relevant Kaveri lines in the
  radeon kernel code."

  Please find attached bug report as requested.
