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