[ INFO: possible irq lock inversion dependency detected ]
2.6.30-rc3-00324-g8087eae #55
---------------------------------------------------------
swapper/0 just changed the state of lock:
(&(&priv->scan_check)->timer){+.-...}, at: [<ffffffff80250d90>]
run_timer_softirq+0x120/0x2e0
but this lock was taken by another, HARDIRQ-safe lock in the past:
(&priv->lock){-.-...}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
