I have something that looks like a regression in bonding between 2.6.26.8 and 2.6.27.6 (I'll try the mid-steps later). Setup: LACP bond(mode=4,mmimon=100) with 3 NIC's and dhcp on top (static ip didn't work either). Problem: The bond doesn't get up after bootup. Subsequence ifdown/ifup brings it up. I suspect it it timing related. The interface being configured before it's ready: root@quad01:~# dmesg | egrep '(dhc|bond)' [ 12.421963] bonding: MII link monitoring set to 100 ms [ 12.483370] bonding: bond0: enslaving eth0 as a backup interface with an up link. [ 12.523372] bonding: bond0: enslaving eth1 as a backup interface with an up link. [ 12.611731] bonding: bond0: enslaving eth2 as a backup interface with a down link. [ 12.780816] warning: `dhclient3' uses 32-bit capabilities (legacy support in use) [ 15.720491] bonding: bond0: link status definitely up for interface eth2. [ 87.800324] bond0: no IPv6 routers present The setup is a 3 NIC bond on a Sun X2200 dual-cpu Quad-core server. I have similar bond on a X4600 where they works with 2.6.27.6 so I suspect that the difference is that the X4600 has all NIC's from the same vendor where as the X2200 has 2 Broadcom NIC's and 2 NVidia nics. root@quad01:~# lspci | grep -i ethernet 00:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3) 00:09.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3) 06:04.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3) 06:04.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3) -- Jesper
