igb 检测到 Tx 单元挂起

有一个：

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty

使用 kenel 3.16.0-46-generic。

今天我进行了 dist-upgrade 并且内核升级到了 3.16.0-48-generic 版本。

重启后我得到了这个：

此后所有网络连接均中断。系统仍然无法使用。

只有在使用旧版 linux-image-3.16.0-46-generic 启动后，我的生产邮件服务器才能工作。

对我来说这是一个严重的错误，有人可以帮助我吗？

答案1

我决定切换到一个新的 Vivid 内核，这是 Ubuntu 14.04.3 LTS 全新安装时的默认内核：

sudo apt-get install linux-signed-generic-lts-vivid

就我而言，因为有 UEFI BIOS 和

sudo apt-get install linux-generic-lts-vivid

对于旧式 BIOS 的情况。

乌托邦内核可以被删除。

答案2

升级到 3.16.0-48 后出现同样的问题。

我们使用的是 Intel S2600GZ4 服务器，配有 4 个 Intel I350 千兆以太网。我们不得不强制 Grub 启动 3.16.0-46 来解决这个问题。

答案3

我正在将我的经验添加到这个帖子中以使其更加完整。

我的经验是，升级到内核 3.16.0-48 后，网络适配器几乎无法使用。我甚至无法完成apt-get update。

我跟着此主题运行命令ethtool -K eth0 gso off gro off tso off。然后我成功完成了apt-get upgrade将 linux ternel 升级到 3.16.0-49。重启后问题就消失了。我不确定ethtool -K eth0 gso off gro off tso off此时该命令是否有帮助。

apt-get upgrade我的看法是，即使你没有完成，你仍然可以运行apt-get update。
