Comment # 43 on bug 1177428 from Takashi Iwai

Now can people wit Picasso board test the kenrel-firmware-amdgpu package in OBS
Kernel:HEAD repo?  I didn't revert the amdgpu there yet, but there was some
error about the split / copy script and it was fixed at first.

Please make sure that you clear /lib/firmware/updates/* and uncompressed
/lib/firmware/amdgpu/picasso* files beforehand.

If the boot still fails with this version, let's check again the following:

- Uncompress /lib/firmware/amdgpu/picasso*.xz, and retest
  unxz -f /lib/firmware/amdgpu/picasso*.xz
  mkinitrd
  reboot

If it still fails,
- Compare the contents of those uncompressed picasso* firmware files with the
20.40 version of the tarball in comment 30.  All those must be identical.
