Hi, Linda
Do you have the BUG log after applied this patch?
bond->lock seems to be the only one who will add the preempt_count, the

And have you tried the 3.9.0-rc1, is the issue still exist?

But do you have the log after applied the change which unlock bond->lock
before enter bond_update_speed_duplex() ? you mentioned that the fix
doesn't address the problem, but I'd like to take a look at the log, may
be there will be more clue ;-)
And have you tried 3.9.0-rc1? may be the issue already solved.

And both bond_enslave() and bond_mii_monitor() are using bond_update_speed_duplex()
with preempt disabled.
Along with the changes in bond_enslave(), I think you also need this (untested):
diff --git a/drivers/net/bonding/bond_main.c b/drivers/net/bonding/bond_main.c

So that means bond lock is the reason, nice, but this is really not a
good fix if we just unlock it...
The better way is to move the cycle wait logical out of the
bond_update_speed_duplex() IMO, I think we need the folk who work on
this driver to make the decision ;-)

You're right, we can't unlock bond->lock while in bond_for_each_slave(),
however I think we don't even need that bond_update_speed_duplex() in
bond_miimon_commit() - cause the speed/duplex on interface state change
were already updated via NETDEV_UP/CHANGE event in
bond_slave_netdev_event() - and if not, it's not our fault, but the
driver's that he didn't call the notifiers.
So, maybe something like this would work (any feedback welcome, it's
definitely not the first time we hit the wall with sleeping in
bond_update_speed_duplex):
Subject: [PATCH] bonding: don't call update_speed_duplex() under spinlocks
bond_update_speed_duplex() might sleep while calling underlying slave's
routines. Move it out of atomic context in bond_enslave() and remove it
from bond_miimon_commit() - it was introduced by commit 546add79, however
when the slave interfaces go up/change state it's their responsability to
fire NETDEV_UP/NETDEV_CHANGE events so that bonding can properly update
their speed.
