Call trace related to bond_mii_monitor  as described in this thread - was seen on 2.6.34 kernel.
(Trace is similar to what is described in the post dated 2009-12-17
21:31:36.) The trace is seen when the network service is stopped. The
issue occurs when the network service is started and stopped in quick

Bonding device configuration parameters are as below -

Bonding driver version:3.6.0
Mode: balance-alb (issue is also seen with active-backup mode)
3 slaves with link up and one slave with link down.

Though this requires more thought and investigation, I thought this
could be a good data point. The below change to the bonding driver
seemed to make the issue go away -

drivers/net/bonding/bond_main.c |    2 +-
 1 files changed, 1 insertions(+), 1 deletions(-)


Any thoughts ?

With regards,
Narendra K
