Cc: danmei.wei@alcatel-sbell.com.cn 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 Hi all, When I run linux kernel ver2.6.10 built by myself, there was a kernel panic when loading E1000 device driver. (See the details below.) Then I built E1000 device driver as a loadable module and insmod it in /etc/rc.d/rc3.d, the ethernet device worked well. I would like to know what the difference is between loadable modules and built-in drivers to the kernel. Does anyone encounter this kind of problems? Thanks!
