If the GPU locks up, the output of intel_error_decode is often more interesting than intel_gpu_dump (unless the kernel hasn't noticed yet). If X is able to restart properly, it indicates that the GPU is working which may be because its state has been reset. dmesg is most interesting with drm.debug=0x02 (which turns on the drm driver debugging. Not sure if that is what you used.
