Hi Thomas et al
Reporting potential lock inversion with 2.6.31-rc3-rtx

=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.31-rc3-rt1 #1
---------------------------------------------------------
canberra-gtk-pl/3110 just changed the state of lock:
((raw_spinlock_t *)(&lock->wait_lock)){+...-.}, at: [<ffffffff8108c4f8>] do_fu1
but this lock was taken by another, HARDIRQ-safe lock in the past:
(&irq_desc_lock_class){-.....}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
1 lock held by canberra-gtk-pl/3110:
#0: (&futex_queues[i].lock){+.+...}, at: [<ffffffff8108c421>] do_futex+0x5b7/1
the first lock's dependencies:

[ INFO: possible irq lock inversion dependency detected ]
2.6.31-rc3-rt1 #1
---------------------------------------------------------
canberra-gtk-pl/3583 just changed the state of lock:
((raw_spinlock_t *)(&lock->wait_lock)){+...-.}, at: [<ffffffff8108c4f8>] do_futex+0x68e/0x961
but this lock was taken by another, HARDIRQ-safe lock in the past:
(&irq_desc_lock_class){-.....}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
1 lock held by canberra-gtk-pl/3583:
#0: (&futex_queues[i].lock){+.+...}, at: [<ffffffff8108c421>] do_futex+0x5b7/0x961
the first lock's dependencies:
