Hello All.

Last night i created a bond mode 4 802.3ad on my NIC.
Running Slackware 14 x86_64
Linux oscuridad 3.2.45 #1 SMP Fri May 31 20:05:26 CDT 2013 x86_64 Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz GenuineIntel GNU/Linux


Here is what I have:

root@oscuridad:/etc/rc.d# cat rc.bond
#!/bin/sh

case "$1" in
'start')
echo "start bond0"
/sbin/modprobe bonding mode=4 miimon=100
/sbin/ifconfig bond0 up
/sbin/ifenslave bond0 eth1
/sbin/ifenslave bond0 eth2
#You don't necesarily need to change the hardware address
#It will take it from the first hardware interface
#ifconfig bond0 hw ether 00:16:3e:aa:aa:aa
;;
'stop')
/sbin/ifconfig bond0 down
/sbin/rmmod bonding
;;
*)
echo "Usage: $0 {start|stop}"
;;
esac
root@oscuridad:/etc/rc.d#

The next line I am posting only the relevant information to keep it short...

root@oscuridad:/etc/rc.d# cat rc.inet1.conf

Now when I do an ifconfig it show a lots of drops..... and in some cases errors....

root@oscuridad:/etc/rc.d# ifconfig

The switch is configured properly for LACP and all is working well with another Linux system running Debian.

Any ideas?

TIA!

Forgot to mention that the NIC is a:

02:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
02:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

and is using the gib kernel module.

Any body?
