[ INFO: possible irq lock inversion dependency detected ]
- ---------------------------------------------------------
rmmod/1514 just changed the state of lock:
(hcd_data_lock){-+..}, at: [<dfca30bf>] hcd_endpoint_disable+0x3f/0x140
[usbcore]
but this lock was taken by another, hard-irq-safe lock in the past:
(&ohci->lock){++..}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
