It looks like 

static int bo_is_busy(struct radeon_bo_int *boi, uint32_t *domain) {...}
in radeon_bo_gem.c:220 (libdrm) 

returns that a bo is not busy but the bo is still mapped and in use. 

That's why the bo with the valid pointer gets from bo_wait list to the bo_free
list and is reused while still used by another part -> crash!
