[SOLVED] e1000e and 82579V: "Device not found"

[pgu]

I just installed Gentoo on a Intel NUC. However I can't get the network interface working.

Whenever I run ifconfig I get:

Code: Select all

# ifconfig eth0
eth0: error fetching interface information: Device not found

When I boot it detects the interface. Here from dmesg:

Code: Select all

[    1.362605] e1000e: Intel(R) PRO/1000 Network Driver - 2.1.4-k

If I do lspci I see that it's the attached driver:

Code: Select all

00:19.0 Ethernet controller: Intel Corporation 82579V Gigabit Network Connection (rev 04)
        Subsystem: Intel Corporation Device 2044
        Kernel driver in use: e1000e

I do not see the following message in dmesg (this is from my laptop which has the same NIC):

Code: Select all

[24455.643354] e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx

However it works when I boot from the livecd usb stick. The installed kernel is 3.7.10. The one on the usb stick is 3.2.12. I have compiled the driver into the kernel(which I have on my laptop too).

Any ideas of what the problem might be?

Is there a way to prevent the clearing of the screen prior to the login prompt? Now I don't have a chance to read the boot messages on the console as it boots in just a second. I just see that something is red...

You've probably fallen victim to the udev upgrade and predictable network interface names

yes ... add --noclear to /etc/inittab

Code: Select all

c1:12345:respawn:/sbin/agetty --noclear 38400 tty1 linux

best ... khay

Thanks. That showed the same message, i.e. eth0 was not found...

Even though I did not do an upgrade (unless the udev 200 was pulled in by something else), but rather a fresh install. I followed the installation handbook which is using eth0, whereas on my new system it's eno1.

Thanks! The problem was solved by replacing eth0 with eno1.
