解决CentOS 6.6 安装遇到网卡问题

情况是,当主机安装完 CentOS 6.6 后,使用 SSH 操作一段时间,连线突然中断,再来就 ping 不到,本机也 ping 不到同网段的,本机自 ping 自已的 ip 就可以.

而 message 出现:

Nov 22 20:34:12 st kernel: e1000e 0000:07:00.0: eth0: Timesync Tx Control register not set as expected

解决方式是要在 /boot/grub/grub.conf ?加入 pcie_aspm=off

kernel /vmlinuz-xxxxxxxxxxxxxxxxxx ro root=xxxxxxxxxxxx pcie_aspm=off
