Hi,
we have a report of WARNING from 3.7.6 in nouveau at drivers/gpu/drm/nouveau/core/core/mm.c:242 here: https://bugzilla.novell.com/show_bug.cgi?id=802347#c11
There is an order 4 allocation failure in nouveau_drm_open -> nouveau_vm_create, i.e. this one failed: vm->pgt = kcalloc(vm->lpde - vm->fpde + 1, sizeof(*vm->pgt), GFP_KERNEL);
Then, on the error path in still in nouveau_drm_open, it is followed by a call to nouveau_cli_destroy. But that one calls nouveau_vm_ref -> nouveau_mm_fini -> nouveau_vm_del -> nouveau_mm_fini which triggers the warning.
Any ideas?
thanks, -- js suse labs
