Yeah, the driver wasn't changed about this. Basically it's a warning message that CPU usage got higher due to somehow wrongly behaving hardware. The driver behavior itself didn't do anything wrong. That is, if the driver didn't show it, you wouldn't have noticed any change (or noticed improvements in some apps :) Of course, it would be ideal if we can add a perfect workaround for it, but right now, I have no idea what to do better. So, I don't think it's worth to keeping this open as a regression. thanks, Takashi From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1752890AbYIMRXT (ORCPT ); Sat, 13 Sep 2008 13:23:19 -0400 Received: (majordomo@vger.kernel.org) by vger.kernel.org id S1751380AbYIMRXH (ORCPT ); Sat, 13 Sep 2008 13:23:07 -0400 Received: from cantor2.suse.de ([195.135.220.15]:41316 "EHLO mx2.suse.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751215AbYIMRXG (ORCPT ); Sat, 13 Sep 2008 13:23:06 -0400 Date: Sat, 13 Sep 2008 19:23:03 +0200 Message-ID: From: Takashi Iwai To: Frans Pop Cc: "Rafael J.
