Message-ID: <20030718233631.F31074@guldivar.globalwire.se> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi! I've seen the discussion regarding high interrupt / system load on the ICH5 SATA and I'm asking what todo about it if I can't put my BIOS into "normal" mode. This machine is an Dell Precision 360 and for some stupid reason they have for this model removed the possibility in the BIOS to change this sort of things (you can't change much really). I'm using 2.4.21-ac4. Just to extract a simple tar file brings the system load up and the computer is slow...
