Date: Mon, 18 Feb 2013 11:27:43 +0100 From: Jiri Slaby <jslaby@...e.cz> To: Marcin Slusarz <marcin.slusarz@...il.com>, bskeggs@...hat.com CC: dri-devel@...ts.freedesktop.org, LKML <linux-kernel@...r.kernel.org> Subject: WARNING: at drivers/gpu/drm/nouveau/core/core/mm.c:242 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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
