Hi Ondrej

While I have not been able to test the 5.2 kernel on my Fedora system I have
installed the 5.3 kernel from rawhide and am seeing the same results:

[root@envy ~]# cp /home/XXX/raven_dmcu.bin /usr/lib/firmware/amdgpu/
[root@envy ~]# dracut -f --kver 5.3.0-0.rc0.git2.2.fc31.x86_64
[root@envy ~]# reboot

Tested on HP ENVY x360 Convertible 15-bq1xx/83C6, BIOS F.20 12/25/2018
Kernel version 5.3.0-0.rc0.git2.2.fc31.x86_64=20

Installing rawhide kernel on Fedora without debug enabled:
sudo dnf config-manager
--add-repo=3Dhttp://alt.fedoraproject.org/p=
ub/alt/rawhide-kernel-nodebug/fedora-rawhide-kernel-nodebug.repo
sudo yum upgrade
