Possible missing firmware /lib/firmware/rtl_nic/rtl8105e-1.fw for module r8169 with 2.6.39 kernel
Do sudo apt-get install firmware-realtek
and the problem should be solved
There's a solution at http://www.davidgis.fr/blog/index.php?2011/05/06/800--resolu-solved-w-possible-missing-firmware-lib-firmware-rtl_nic-rtl8105e-1fw-for-module-r8169. Essentially you need to do:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/romieu/linux-firmware.git
sudo cp -r linux-firmware/rtl_nic/ /lib/firmware/
and then sudo update-initramfs -u
works without errors.
I had the same problem whit Ubuntu 12.04.5 LTS. Today I have tested, but the old "git://git.kernel.org/pub/scm/linux/kernel/git/romieu/linux-firmware.git" is a broken link.
I have searched the new git url for dowload the firmware of realtek. The commands that I have tested (and works very well) are:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp -r linux-firmware/rtl_nic/ /lib/firmware/
sudo update-initramfs -u
and
rm -rf linux-firmware
For deleting the directory that git has downloaded.
