Thomas there is 2 more bugs: In ttm_bo_mmap if the bo = NULL after ttm_bo_vm_lookup_rb then if (unlikely(bo == NULL)) { printk(KERN_ERR "Could not find buffer object to map.\n"); goto out_unref; } Should be if (unlikely(bo == NULL)) { printk(KERN_ERR "Could not find buffer object to map.\n"); return -EINVAL; } Otherwise you unref a null bo and bad things happen.
In ttm_mem_reg_is_pci i think it should return false if flags TTM_MEMTYPE_FLAG_NEEDS_IOREMAP is not set otherwise kmap on a gart (unmappable to cpu) will think it needs to use ioremap which fails.
