You can try to update the latest firmware on those network cards.
I have a HS20 blade, and I use bonding to do the failover.
for somehow, "Link detected" is not stable(it's stable if I remove bonding).
After I updated it to the latest firmware, "Link detected" is stable.
and bonding is working fine.
