After applying this patch i've got this:

[ INFO: possible circular locking dependency detected ]

ospfd/3984 is trying to acquire lock:
(&ppp->wlock){-...}, at: [<ffffffff803512a0>] ppp_xmit_process+0x20/0x4f0
but task is already holding lock:
(&dev->_xmit_lock){-+..}, at: [<ffffffff8038d778>] __qdisc_run+0x88/0x1c3
which lock already depends on the new lock.
Thanks Yuriy!
As a matter of fact I suspected there will be something more.
Lockdep always stops working after the first warning, and you
have some very interesting (entangled) configuration, so each
fix could uncover new warnings.
I need some time to figure out this one, so I'd try to use your
help yet... I hope it's only about lockdep warnings and there
are no real lockups.
Best regards,
Jarek P.
