Thanks.  It's Picasso board, and this was already a problem in the past, hence
we shipped the older firmware as a workaround.
At the latest kernel-firmware update, we removed the workaround as I was
informed that the issue should have been fixed, but apparently it's not fixed. 
So I'm going to put the old firmware again.

However, the question is which old one; I'd really like to see whether the
original issue (the GPU error at resume) comes from the firmware or not.

Now I uploaded various versions of picasso firmware files taken from
linux-firmware.git.  The tarball contains subdirectory for each version (e.g.
19.50, 20.10, ...).  For testing it, try the following:

- Create /lib/firmware/updates/amdgpu directory:
  % mkdir -p /lib/firmware/updates/amdgpu

- Copy the contents of the firmware version you want to test (e.g. 19.50):
  % cp 19.50/amdgpu/picasso* /lib/firmware/updates/amdgpu/

- Rebuild initrd and retest:
  % mkinitrd
  % reboot

The version 20.40 is the same one as the latest kernel-firmware package, hence
this is supposed to be broken.  I included it to be sure.

Please check each version and let me know the behavior.  Thanks!
