Cc: linux-ide@vger.kernel.org, "Linux Kernel" MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1108 Lines: 32 We see that in ata_piix.c, there is a whitelist for (laptop) Intel ICH controllers with short cables, tied to specific vendor subsystem IDs. Since my mini-ITX Ibase MI910F has the subsystem IDs specified as Intel [1], this is unusable. I can't find another existing mechanism to add short cable information, to allow UDMA/66 for my on-board CF socket. Do you suggest I cook a patch to pass a kernel argument eg 'ich=short' or 'pata=short', or can you think of a better mechanism?
