SLES11 SP1 can crash when a network with bonding devices is stopped
This document (7006170) is provided subject to the disclaimer at the end of this document.
This issue is not limited to the balance-alb bonding mode. This same issue has been seen with the active backup bonding mode, and likely exists for other bonding modes as well.
In case the kernel cannot be upgraded a workaround to avoid this crash is to set the miimon to zero before issuing a network stop command or shutting down the system. This can be done through the sysfs interface.
echo "0"> /sys/devices/virtual/net/bond0/bonding/miimon
This will set miimon to zero for the first network bond. A similar command would be used to set the miimon to zero for any additional network bonds that are setup, changing the bond0 in the path to bond1, bond2, etc.
Checking dmesg can verify that miimon was set to zero: "bonding: bond0: Setting MII monitoring interval to 0."
