Ok. I'll try and work out which patch it is, but in the mean time:

Ethernet Channel Bonding Driver: v3.2.3 (December 6, 2007)

Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

802.3ad info
LACP rate: slow
Active Aggregator Info:
        Aggregator ID: 1
        Number of ports: 1
        Actor Key: 17
        Partner Key: 4
        Partner Mac Address: 00:12:a9:13:3f:67

Slave Interface: eth0
MII Status: down                       <-- this one should be up as well
Link Failure Count: 2
Permanent HW addr: 00:11:43:d7:75:74
Aggregator ID: 2

Slave Interface: eth1
MII Status: up
Link Failure Count: 1
Permanent HW addr: 00:11:43:d7:75:75
Aggregator ID: 1

Bonding options:
options bond0 miimon=100 mode=802.3ad

I'll send the dmesg by private email as its quite large,

Steve.
