解决Dell笔记本更换内存后RedHat AS 4找不到网卡的问题

一台Dell D600笔记本,安装有RedHat AS 4。

原来的内存是512兆(两条256的),更换成1G(1条)后,重启机器,启用网卡时出现错误:Device eth0 has different MAC address than expected, ignoring. 系统启动以后找不到网卡设备。

google以后,在redhat的邮件列表里找到解决办法与大家分享。

先注释掉/etc/sysconfig/network-scripts/ifcfg-eth0中HWADDR=xx:xx:xx:xx:xx:xx这一行。在查看文件/etc/modprobe.conf,得知eth0的模块名tg3。用lsmod查看,没有发现tg3这个module。

执行如下命令:

# depmod -a
# modprobe -v tg3

然后,重启网络

# service network restart

问题解决。
