in /etc/modprobe.conf
alias bond0 bonding
alias bond1 bonding
options bonding max_bonds=2
options bond0 mode=1 arp_interval=30000 arp_ip_target=192.168.0.1 primary eth1
options bond1 -o mode=1 arp_interval=30000 arp_ip_target=10.0.0.1 primary=eth4

after service network restart eth4 pukes all over the console and an ifconfig eth4 shows the mac address of his partner in bond

New What kind of NICs?
If they are Broadcom... they have a history for doing that.

Its a driver issue and HP and RedHat have a fix for it.

No matter the make, its a driver memory space issue and pretty much the only way to fix it is to restart the machine.

New Like I said...
HP created a driver patch that RedHat has.

You might contact IBM or RedHat for that same fixup, its not in RedHat v5.x at all as its out of tree patch and hasn't been integrated.

This is a common issue with the problem with the broadcom driver.
