無法讓 Intel I210 乙太網在 Debian wheezy 上執行
我有一台帶有華碩 P9D-I 主機板的伺服器。它有兩個板載 Intel NIC：
# 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)伺服器正在使用最新的反向移植核心執行 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)乙太網介面確實顯示在

我找到了原因——我們
acpi-support安裝了一個軟體包，由於一個錯誤，它啟用了許多不需要的省電功能。顯然igb驅動程序根本不喜歡那些省電設置。我在錯誤報告中描述了詳細資訊：http ://bugs.debian.org/cgi-bin/bugreport.cgi?bug=728692
如果其他人遇到問題：刪除
acpi-support並安裝acpi-support-base.acpi-support電源按鈕仍然可以工作，但是您不希望在伺服器上使用的所有剩餘的省電魔法都消失了。
