The kernel and MESA seems new enough, LLVM is 6 so maybe you should try 7. The firmware also looks pretty late but I still would advise to manually override all firmware files with files from here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu Just backup your existing firmware/amdgpu folder for any case. > > > BTW: In a forum somebody asked what the dmesg output on crash looked like if > I enabled amdgpu.gpu_recovery=1 - the result is a few lines more of output, > but still a fatal system crash: > > Jun 26 00:50:09 ryzen kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* > ring gfx timeout, last signaled seq=12277, last emitted seq=12279 > Jun 26 00:50:09 ryzen kernel: [drm] IP block:gmc_v8_0 is hung! > Jun 26 00:50:09 ryzen kernel: [drm] IP block:gfx_v8_0 is hung! > Jun 26 00:50:09 ryzen kernel: amdgpu 0000:0a:00.0: GPU reset begin! > Jun 26 00:50:15 ryzen kernel: [drm:drm_atomic_helper_wait_for_flip_done > [drm_kms_helper]] *ERROR* [CRTC:42:crtc-0] flip_done timed out > Jun 26 00:50:15 ryzen kernel: [drm:drm_atomic_helper_wait_for_dependencies > [drm_kms_helper]] *ERROR* [CRTC:42:crtc-0] flip_done timed out > Jun 26 00:50:25 ryzen kernel: [drm:drm_atomic_helper_wait_for_dependencies > [drm_kms_helper]] *ERROR* [PLANE:40:plane-4] flip_done timed out It's a know issue, try the patch I attached to resolve the deadlock , but you will probably experience other failures after that anyway.
