Subject: Deadlock after info soft-safe -> soft-unsafe lock order detected
Hi
With todays kernel build I've got this trace which followed deadlock of my box.
(T61, 2GB, inel graphics)
glxgears:3427 map pfn expected mapping type write-back for
e2800000-e337c000, got uncached-minus
glxgears:3427 freeing invalid memtype e2800000-e337c000
======================================================
[ INFO: soft-safe -> soft-unsafe lock order detected ]
2.6.28 #102
------------------------------------------------------
firefox/3654 [HC0[0]:SC0[1]:HE1:SE0] is trying to acquire:
(&fbc->lock){--..}, at: [<ffffffff803aa578>] __percpu_counter_add+0x58/0x80
and this task is already holding:
(slock-AF_INET){-+..}, at: [<ffffffff804dd578>] tcp_close+0x198/0x4d0
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:
[<ffffffffffffffff>] 0xffffffffffffffff
to a soft-irq-unsafe lock:
(&fbc->lock){--..}
... which became soft-irq-unsafe at:
