From: David Miller X-Mailer: Mew version 5.1.52 on Emacs 21.4 / Mule 5.0 (SAKAKI) Mime-Version: 1.0 Content-Type: Text/Plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I've been noticing this off and on for the past week or so. The system seems to jam up for several seconds, anything that would need to read from disk just sits there during this time. I think it's correlated with generating a lot of dirty write data. My mouse moves around in X etc. so it really is only processes that need to read from disk that get stuck. Perhaps it's a side effect of those dirty ratio changes Linus made to start off the 2.6.22 merge cycle?
