[ 4573.319728] ---------------------------------------------------------
[ 4573.319735] swapper/0 just changed the state of lock:
[ 4573.319741] (&(&priv->scan_check)->timer){+.-...}, at:
[<ffffffff81044e1b>] run_timer_softirq+0x13c/0x26e
[ 4573.319766] but this lock was taken by another, HARDIRQ-safe lock
in the past:
[ 4573.319772] (&priv->lock){-.-...}
[ 4573.319779]
[ 4573.319781] and interrupts could create inverse lock ordering between them.
[ 4573.319784]
[ 4573.319790]
[ 4573.319791] other info that might help us debug this:
[ 4573.319798] no locks held by swapper/0.
