Let's try to get some debug info for the VMC page fault then - Clone and build our open source register analyzer from here - https://cgit.freedesktop.org/amd/umr/ Install trace-cmd utility Load driver with cmd line parameter amdgpu.vm_fault_stop=2 from grub P.S Best to use latest kernel from here - https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next After desktop is loaded type sudo trace-cmd start -e dma_fence -e gpu_scheduler -e amdgpu -v -e "amdgpu:amdgpu_mm_rreg" -e "amdgpu:amdgpu_mm_wreg" -e "amdgpu:amdgpu_iv" to enable kernel event tracing log If possible to launch the game from shell then prepend the command with GALLIUM_DDEBUG=always to dump all the MESA commands into files in ~/ddebug_dumps/ Start the game. When the problem happens do the following - as root cd /sys/kernel/debug/tracing && cat trace > event_dump as normal user or root sudo umr -lb > umr_dump sudo umr -O verbose,use_colour -R gfx[.] >> umr_dump sudo umr -O halt_waves,use_colour -wa >> umr_dump dmesg > dmesg_dump Upload a tar/zip of all those files + all the files from ~/ddebug_dumps/
