Unpatched 2.6.24-rc5 with "echo -n eth0 > /sys/class/net/${IFACE}/bonding/primary"
removed, still has this issue. I also removed:
# echo -n 1 > /sys/class/net/${IFACE}/bonding/mode
# echo -n 100 > /sys/class/net/${IFACE}/bonding/miimon
but this did not help:
bonding: bond0: setting mode to active-backup (1).
bonding: bond0: Setting MII monitoring interval to 100.
ADDRCONF(NETDEV_UP): bond0: link is not ready
bonding: bond0: Adding slave eth0.
e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
bonding: bond0: making interface eth0 the new active one.
bonding: bond0: first active interface up!
bonding: bond0: enslaving eth0 as an active interface with an up link.
bonding: bond0: Adding slave eth1.
ADDRCONF(NETDEV_CHANGE): bond0: link becomes ready
=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.24-rc5 #1
---------------------------------------------------------
events/0/9 just changed the state of lock:
(&mc->mca_lock){-+..}, at: [<c0411c52>] mld_ifc_timer_expire+0x130/0x1fb
but this lock took another, soft-read-irq-unsafe lock in the past:
(&bond->lock){-.--}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
