eth0 error messages

Q After installing Mandrake 10.1, eth0 is running well. However after reboot, I get this message: "Bringing up eth0: FAILED". Help!

A For both eth0 and eth1, there are packets being transmitted but nothing being received. This suggests that DHCP requests are sent out but not responded to. Running dhclient from the command line to manually request an IP address for eth0 will output useful information, such as link failure or errors. Why there is a 127.255.255.255 address on eth0:9 is anyone's guess. Checking out /etc/sysconfig/network-scripts and removing ifcfg-eth0:9 should remove this because it will interact with traffic on the loopback address of 127.0.0.1 since the netmask 255.0.0.0 includes this IP. While the kernel does detect the Ethernet card, it doesn't suggest that it's working correctly. Running dmesg will show any kernel messages, indicating a timeout or other driver failure causing issues with DHCP.
