CentOS5： Device eth0 has different MAC address than expected

Centos/linux重启出现错误信息：
Device eth0 has different MAC address than expected

应该是dmesg 和 eth0 配置文件之间的冲突。

[[email protected] ~]# dmesg | grep eth0
divert: allocating divert_blk for eth0
eth0: RTL-8139C+ at 0xd0842000, 40:61:86:ED:25:E7, IRQ 11

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=40:61:86:ED:35:17
ONBOOT=yes
TYPE=Ethernet
IPADDR=192.168.122.101

GATEWAY=192.168.122.1

改正很简单，HWADDR=40:61:86:ED:35:17 改成正确的40:61:86:ED:25:E7 就OK了

HWADDR=40:61:86:ED:25:E7

如果你用dmesg | grep eth0这个命令看不到MAC地址的话，可以用ifconfig eth0这个命令来看。看到就记录下来，在ifcfg-eth0中改就可以了。
