Attansic L1

All CentOS versions released after June 2010 include proper drivers for this chipset so all the below information is obsolete. If run a recent CentOS version and you encounter issues with an Attansic wired network card, please consider installing the package kmod-atl1 distributed by the ElRepo 3rd party repository. See https://wiki.centos.org/AdditionalResources/Repositories for details.

1. Hardware

The Attansic L1 is included as the onboard network device for many mainboards

2. Problem

No version of Centos <= 5.6 includes a driver for this chipset.

3. In-Depth explanation

The driver for this chipset has been merged in the mainline kernel in Feb 2007, as of kernel version 2.6.20-git5. Centos <=5.6 uses older kernels for which no backport exists yet.

4. Output of `lspci -v`

02:00.0 Ethernet controller: Attansic Technology Corp. L1 Gigabit Ethernet Adapter (rev b0)

5. Solution

There is a driver available from http://atl1.sourceforge.net/. Quoting that site:

According to your needs, you can select one of the following solutions:

5.1. Update to a more recent CentOS release

Since CentOS 5.7, the driver for this chipset is included in the kernel.

5.2. Prebuilt kernel module

The driver may also be downloaded as a kABI tracking kmod RPM package from the ELRepo repository. Select the kmod package that matches your kernel and install it according to the instructions provided by that repository.
