我有一台带有华硕 P9D-I 主板的服务器。它有两个板载 Intel 网卡：
# lspci -nn | grep Eth
01:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:1533] (rev 03)
02:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:1533] (rev 03)
服务器正在运行带有最新向后移植内核的 Debian wheezy：
# cat /etc/debian_version
7.2
# uname -a
Linux hostname 3.10-0.bpo.3-amd64 #1 SMP Debian 3.10.11-1~bpo70+1 (2013-09-24) x86_64 GNU/Linux
# dpkg -l | grep -E '(linux-image-amd64|linux-image-3.10)'
ii linux-image-3.10-0.bpo.3-amd64 3.10.11-1~bpo70+1 amd64 Linux 3.10 for 64-bit PCs
ii linux-image-amd64 3.10+52~bpo70+1 amd64 Linux for 64-bit PCs (meta-package)
以太网接口做出现在ifconfig -a：
# ifconfig -a

[...]
但由于某种原因，我实际上无法将它们用于任何用途：
# ifconfig eth0 up
SIOCSIFFLAGS: No such device
# ifconfig eth1 up
SIOCSIFFLAGS: No such device
# ethtool eth0
Settings for eth0:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available
# ethtool eth1
Settings for eth1:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available
dmesg负责的司机似乎没有任何有趣的输出igb：

有谁知道这里可能出了什么问题以及如何让这些网卡正常工作？如果可以在不手动编译内核或驱动程序的情况下做到这一点，我会更喜欢这样做。
答案1
我找到了原因 - 我们acpi-support安装的软件包由于错误而启用了许多不需要的省电功能。显然igb司机根本不喜欢这些省电设置。
我在错误报告中描述了详细信息：http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=728692
如果其他人遇到此问题：删除acpi-support并安装acpi-support-base.电源按钮仍然可以工作，但是acpi-support您不希望在服务器上使用的所有剩余节能魔法都消失了。
答案2
Martin 的解决方案工作正常 - 只需确保安装后端口内核，因为稳定内核不支持 Intel I210 NIC：
apt-get -t wheezy-backports install linux-image-amd64
但这可能需要一些时间。
