SubjectRe: 2.6.23-rc2-mm1: irq lock inversion dependency detected
Date
Hello,

And the winner of today is ...



=========================================================
[ INFO: possible irq lock inversion dependency detected ]
2.6.23-rc2-mm1 #7
---------------------------------------------------------
runscript.sh/5843 just changed the state of lock:
(_xmit_ETHER){-+..}, at: [<c03cbe79>] 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 runscript.sh/5843.

the first lock's dependencies:
