    SubjectRe: 2.6.23-rc2-mm2: possible irq lock inversion dependency detected
    Date
    Hello,

    Have fun :)

    =========================================================
    [ INFO: possible irq lock inversion dependency detected ]
    2.6.23-rc2-mm2 #1
    ---------------------------------------------------------
    depscan.sh/5928 just changed the state of lock:
    (_xmit_ETHER){-+..}, at: [<c03cb669>] dev_watchdog+0x17/0xcc
    but this lock took another, soft-irq-unsafe lock in the past:
    (&tp->lock){--..}

    and interrupts could create inverse lock ordering between them.


    other info that might help us debug this:
    no locks held by depscan.sh/5928.

    the first lock's dependencies:
