CentOS - Aug 2007 - machine with 2 ethernet cards e1000 and forcedeth

I am using centos 5 x86_64 AMD64 X2 4200+. I am current on yum update.

My machine has two ethernet cards. e1000 (eth0) and forcedeth (eth1)

[root at fsdsigns2 ~]# more /etc/modprobe.conf
alias eth0 e1000
alias eth1 forcedeth



sometimes on boot the forcedeth driver thinks it is eth0:
[root at fsdsigns2 ~]# dmesg | grep eth
forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.60.
forcedeth: using HIGHDMA
eth0: forcedeth.c: subsystem: 01458:e000 bound to 0000:00:07.0
e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
ADDRCONF(NETDEV_UP): eth1: link is not ready
e1000: eth1: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex, Flow 
Control: RX/TX
ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
eth0: no IPv6 routers present
eth1: no IPv6 routers present




however, sometimes it starts up correctly:
[root at fsdsigns2 ~]# dmesg | grep eth
forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.60.
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
forcedeth: using HIGHDMA
eth1: forcedeth.c: subsystem: 01458:e000 bound to 0000:00:07.0
e1000: eth0: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex, Flow 
Control: RX/TX


How can I get this connection to RELIABLY come up
each time as eth0 is e1000 and eth1 is forcedeth

Thanks,

Jerry

This is a known problem with the forcedeth driver and some of the newer 
ethernet controllers it is used on. There is supposed to be a patch coming in 
the latest 2.6 kernel, but who knows how long it might take to be backported 
by upstream. Does your board manufacturer supply a linux driver?

 From the RHEL4 docs (also applicable to C5): 
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/ref-guide/s1-networkscripts-interfaces.html

HWADDR=<MAC-address>, where <MAC-address> is the hardware address of
the
Ethernet device in the form AA:BB:CC:DD:EE:FF. This directive is useful 
for machines with multiple NICs to ensure that the interfaces are 
assigned the correct device names regardless of the configured load 
order for each NIC's module. This directive should /not/ be used in 
conjunction with MACADDR.

You can get the mac address from running ifconfig. The HWADDR setting 
goes in the /etc/sysconfig/network-scripts/ifcfg-eth0 (and ifcfg-eth1) 
files. (the setting either doesn't exist, or may be transposed and 
causing your problems)
