Debian Kernels and Tigon TG3 Firmware

If you are updating the kernel on your Debian 5.0 (Lenny) or Debian 6.0 (Squeeze) installation and have a Tigon Gigabit ethernet controller, such as the one on the Dell Poweredge T110, you may receive the following warning messages:

W: Possible missing firmware /lib/firmware/tigon/tg3_tso5.bin for module tg3
W: Possible missing firmware /lib/firmware/tigon/tg3_tso.bin for module tg3
W: Possible missing firmware /lib/firmware/tigon/tg3.bin for module tg3

How to fix this problem

1.) Add the “non-free” repository to the sources.lst file.

vim /etc/apt/sources.list
deb http://ftp.us.debian.org/debian/ squeeze main contrib non-free
deb-src http://ftp.us.debian.org/debian/ squeeze main contrib non-free

2.) Update apt-get and install the “firmware-linux-nonfree” package.

apt-get update
apt-get install firmware-linux-nonfree

Upgrading the kernel to 2.6.39 in Debian 6

Some applications require a newer kernel version to make them work better . But the current stable kernel is 2.6.32.

First of all;
1. backup your /boot!

cp /boot /root -R

2. Make changes to your sources.list .

vim /etc/apt/sources.list

3. Add the line below to the bottom of the file.

deb http://backports.debian.org/debian-backports squeeze-backports main

4. Update your repositories

apt-get update

5. Install  the backport and the kernel. (note: the linux headers and other dependencies will be installed aswell)

apt-get install -t squeeze-backports linux-image-2.6.39-bpo.2-amd64

The install will update the grub config aswell, and will put the 2.6.39 kernel at the top (so it will boot first). If all goes well you should reboot the server and the kernel will be loaded.

If the server doesnt reboot and gives you the grub shell . You can try to boot from a live disk, and copy the files from your backup back to /boot of your install.
