With kernel driver amdgpu & [AMD/ATI] Baffin [Polaris11] (radeon RX560). Unfortunately new releases of kernel images crash too. => 4.19 is not anymore the solution vs 4.9.
linux-images 4.9 & 4.19 often (not systematically) crash randomly & always after X started (but I am seldomly a few minutes in console mode). Usually within a few minutes after login. I wonder why a version works, then a newer crashes, even with very different patch application dates, ex: 4.9.135 of 20-Oct-2018 works & 4.19.16 of 16-Jan-2019 works, whereas in between 4.9.144-1 of 08-Dec-2018 crashes. CrashZ (T&C>10, T>C)= (B) + linux-image-4.19.0-0.bpo.4-amd64-unsigned 4.19.28-2~bpo9+1 = upstream 10-Mar-2019 Work (T>>10) = (B) + linux-image-4.19.0-0.bpo.2-amd64-unsigned 4.19.16-1~bpo9+1 = upstream 16-Jan-2019 CrashM (T=C=1) = (B) + linux-image-4.9.0-9-amd64 4.9.161-1 = upstream 27-Feb-2019 Crash = (A) + linux-image-4.9.0-8-amd64 4.9.144-1 = upstream 08-Dec-2018 Work = (A) + linux-image-4.9.0-8-amd64 4.9.135-1 = upstream 20-Oct-2018 CrashZ = hard crashes: Keyboard do not respond anymore & Magic SysRq key do not work. CrashM = Magic SysRq keys work (and allow a safe reboot).
