Killer Ethernet E2400 未连接 16.04

Killer Ethernet E2400 未连接 16.04

我正在使用 Ubuntu 16.04,硬件如下:

# E2400 Killer Ethernet
lspci -nn | grep 0200
04:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)

还有这个版本的ubuntu:

已更新。一切正常,但我将带有千兆以太网控制器的主板换成了带有 E2400 Killer 以太网控制器的新主板。

难道更换硬件导致Ubuntu无法正常工作?

问候,lilEzek。

请参阅此帖子:https://forums.linuxmint.com/viewtopic.php?t=215169海报上有同样的症状;以太网不工作,并显示错误消息:

fatal interrupt 0x200, resetting

他通过在 BIOS 中禁用 IOMMU 解决了这个问题。请尝试一下。如果无效,我们将尝试 GRUB 参数选项。

请打开终端并执行:

gksudo gedit /etc/default/grub

如果您没有文本编辑器 gedit,请使用 nano 或 Kate 或 Leafpad。更改以下行:

GRUB_LINUX_CMD_LINE=""

读书:

GRUB_LINUX_CMD_LINE="iommu=soft"

仔细校对,保存并关闭文本编辑器。让系统重新读取文件并使用更改:

sudo update-grub

一切已准备就绪。
