E-mail: jt@hpl.hp.com From: Jean Tourrilhes Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 72394 Lines: 2311 Hi Marcelo, I've noticed that the attached patch was also not included in 2.4.21-pre2. It's a new driver that replaces the old toshoboe by fixing a mountain of bugs and adding support for newer revisions of the hardware, and is therefore anticipated by people having this hardware (and who don't want to upgrade to 2.5.X). I decided to include this new driver alongside the old driver to be on the safe side. I checked that it applies properly in 2.4.21-pre2, so would you mind applying that to your kernel ? Thanks...
