Bug#908632: linux-image-4.19.0-rc3-amd64-unsigned: kernel 4.19 fails to load amdgpu driver on R9 270X.
Today I had some spare time and I did some tests.
On kernel 4.17 and 4.18 I can switch from radeonsi to amdgpu using/removing 'radeon.si_support=0 amdgpu.si_support=1'
and the system finds and loads the relevant firmware in /lib/firmware/radeon, giving this system a boost in performance,
correct HDMI output and no crashes.
Booting kernel 4.19, the system could not load the relevant firmware when I tried to use amdgpu, but booted using radeonsi.
Today I did copy all the firmware in '/lib/firmware/radeon' to '/lib/firmware/amdgpu' and the system booted in a working
state and has been stable for the last hour.
Since it is possible to use amdgpu with older GCN cards, the kernel should also look for the firmware inside
'/lib/firmware/radeon' when using 'amdgpu' driver.
'$ cat /var/log/syslog' of this working session with kernel 4.19-rc3 and 'cp /lib/firmware/radeon/* /lib/firmware/amdgpu'
