Hi! Did as you suggested: # apt purge firmware-amd-graphics # rm -rf /lib/firmware/amdgpu # apt install firmware-amd-graphics Then I copied file by file, restarting the system between each copy until I got a working graphical environment. The files needed for me are: pitcairn_mc.bin pitcairn_smc.bin pitcairn_pfp.bin pitcairn_me.bin pitcairn_ce.bin pitcairn_rlc.bin Would you like me to test anything else? Regards, Felipe.

Bug#908632: linux-image-4.19.0-rc3-amd64-unsigned: kernel 4.19 fails to load amdgpu driver on R9 270X.
The problem persists on linux-image-4.19.0-rc6-amd64-unsigned and linux-image-4.19.0-rc7-amd64-unsigned. The workaround mentioned above still fixes the problem on my end.
Bug#908632: linux-image-4.19.0-rc3-amd64-unsigned: kernel 4.19 fails to load amdgpu driver on R9 270X.
Tested again with experimental kernel 4.19-rc4 and the result is the same (not able to find firmware) as with 4.19-rc3 and 4.19-rc2. Tried reinstalling the firmware-amd-graphics and firmware-linux packages. Booting with kernel parameters 'radeon.si_support=0 amdgpu.si_support=1' and kernel 4.19.rc-4 the system bails and cannot find the required firmware which is located at '/lib/firmware/radeon'. If I copy the contents of '/lib/firmware/radeon' to '/lib/firmware/amdgpu' and restart, the system boots, loads the firmware and works. Since previous kernels (4.17, 4.18) the system had no problem finding the correct firmware inside '/lib/firmware/radeon' when using amdgpu driver.

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.

Thanks for the response, Bastian! I have been using this option since kernel 4.15, when the AMD Display Code was merged. Without these options the card would panic and the system would crash.

Bug#908632: linux-image-4.19.0-rc3-amd64-unsigned: kernel 4.19 fails to load amdgpu driver on R9 270X.
Package: src:linux Version: 4.19~rc3-1~exp1 Severity: important Dear Maintainer, The system fails to load amdgpu driver with linux-image-4.19-rc{2,3}-amd64-unsigned, making it impossible to start X session. If I boot without 'radeon.si_support=0 amdgpu.si_support=1' the system boots, I can start X session but it becomes unstable and eventually X crashes. Booting from kernel 4.18.6 makes it work again. -- Package-specific info: ** Version: Linux version 4.19.0-rc3-amd64 (debian-ker...@lists.debian.org) (gcc version 8.2.0 (Debian 8.2.0-6)) #1 SMP Debian 4.19~rc3-1~exp1 (2018-09-10) ** Command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-rc3-amd64 root=UUID=a1b73323-8a0d-46ad-9723-72b1f6ca6962 ro apparmor=1 security=apparmor amd_iommu=on iommu=pt quiet radeon.si_support=0 amdgpu.si_support=1 amdgpu.dc=1 radeon.dpm=0 amdgpu.dpm=1 ** Tainted: E (8192) * Unsigned module has been loaded. ** Kernel log: [9.147023] EXT4-fs (sdb1): mounted filesystem with ordered data mode.
