Could you please check if under /sys/kernel/debug You can find a ttm directory under that hierarchy and a ttm_shrink file? Is anything writing to the file (like the game?) With nokaslr, do you see a change in the game characteristics, like more simulated objects (an increase in fleet size, simulated objects)? It might be interesting to debug the ttm_pages_limit to see if that changes when nokaslr is enabled as well Thanks! Balbir
