Linux e1000e（英特尔网络驱动程序）问题多多，我该从哪里开始？

我目前e1000e在 Ubuntu Maverick (1.0.2-k4) 中遇到了一个大问题（根本无法工作），恢复后我在 dmesg 中收到了很多东西：

[ 9085.820197] e1000e 0000:02:00.0: PCI INT A disabled

答案1

请尝试使用内核参数启动内核pcie_aspm=off。

答案2

来自英特尔的驱动程序自述文件：downloadmirror.intel.com/9180/eng/README.txt

82573 (V/L/E) TX 单元挂起消息

在使用 e1000 驱动程序正常运行期间，带有 82573 芯片组的多个适配器会显示“TX unit hang”消息。启用和禁用 TSO 时都会出现此问题，这是由 EEPROM 中启用的电源管理功能引起的。早期向供应商发布的芯片组具有启用此功能的 EEPROM 位。发现此问题后，发布了较新的适配器，并在 EEPROM 中禁用了此功能。

如果您在适配器中遇到问题，并且芯片组是基于 82573 的，则可以使用 ethtool 验证适配器是否需要修复：

 # ethtool -e eth0
 Offset          Values
 ------          ------
 0x0000          00 12 34 56 fe dc 30 0d 46 f7 f4 00 ff ff ff ff
 0x0010          ff ff ff ff 6b 02 8c 10 d9 15 8c 10 86 80 de 83
                                                           ^^

偏移量 0x001e (de) 处的值的位 0 未设置。这会启用有问题的省电功能。在这种情况下，EEPROM 需要在偏移量 0x001e 处读取“df”。

一次性 EEPROM 修复可用作 shell 脚本。此脚本将验证适配器是否适用于修复以及是否需要修复。如果需要修复，它会将更改应用于 EEPROM 并更新校验和。如果对 EEPROM 进行了更改，则用户必须在应用修复后重新启动系统。

脚本输出示例：

 # bash fixeep-82573-dspd.sh eth0
 eth0: is a "82573E Gigabit Ethernet Controller"
 This fixup is applicable to your hardware
 executing command: ethtool -E eth0 magic 0x109a8086 offset 0x1e value 0xdf
 Change made. You *MUST* reboot your machine before changes take effect!

该脚本可以在以下网址下载： http://e1000.sourceforge.net/files/fixeep-82573-dspd.sh

答案3

作为一个掘墓人，我想挖出这个老帖子来分享我针对 Ubuntu 的解决方案。下载最新的英特尔网络驱动程序（3.4.0.2在撰写本文时）。解压它，将一个内容附加到 Makefile 中的一行，获取补丁，应用补丁，安装，重新添加模块，最后重新启动。祝你好运。

sudo rmmod e1000e && sudo modprobe e1000e
sudo reboot

本 wad 在 Ubuntu 18.04、内核 4.15 上完成。

答案4

我在 Ubuntu 18.04.1、4.15.0-36 内核上的 e1000e 上遇到了同样的问题，但没有任何帮助。我已将驱动程序直接从英特尔更新到 3.4.2.1-NAPI，没有任何改进。本文和其他线程没有帮助。通过阅读猜测这个 Ubuntu 错误报告我想到了一个解决方法，可以显著减少环形缓冲区的大小：

sudo ethtool -G eth0 rx 256 tx 256

这为我彻底解决了这个问题，而且似乎根本不影响性能（桌面使用，只做了基本的基准测试）。
