hi,

I am hitting this with git of yesterday or maybe day before yeseterday.
(top SHA is b58602a4bac012b5f4fc12fe6b46ab237b610d5d)

I am still not sure how to reproduce it.

thanks,

[ INFO: soft-safe -> soft-unsafe lock order detected ]
2.6.28 #2
------------------------------------------------------
firefox/3695 [HC0[0]:SC0[1]:HE1:SE0] is trying to acquire:
(&fbc->lock){--..}, at: [<c0548cf7>] __percpu_counter_add+0x52/0x7a

and this task is already holding:
(slock-AF_INET){-+..}, at: [<c06adb82>] tcp_close+0x1a4/0x347
which would create a new lock dependency:
(slock-AF_INET){-+..} -> (&fbc->lock){--..}

but this new dependency connects a soft-irq-safe lock:
(slock-AF_INET){-+..}
... which became soft-irq-safe at:
