There are two bugs that I know can cause GPU hang: - changing screen resolution in some games, - out of memory condition: not sure about the reason but I think that somewhere in the texture code the bo's isn't unreferenced so the memory isn't freed (Glisse suggested that maybe the same bo is used few times in the same cs so the cs_write_reloc refs it every time, but radeon_validate_reset_bos unrefs it only once). I think it is probably the second one, because I hit it with many games. It's easy to check: decrease texture detail or depth and if the game will hang little bit later that's it.
