You're welcome.
Not the exact same problem, no. I can get a hard-lock by trying to use amdvlk to play rpcs3, but it doesn't produce the same error and it's not as consistent (takes up to 15 minutes to crash)
Not sure if it's worth noting but I went back and tried every Cemu version back to 1.5 and a lot of wine versions going back to 2.8. It happens every time as soon as the game loads.
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/
