3c59x.c's vortex_timer() function knows that vp->lock can only be used
by an irq context that it disabled - and can hence take the vp->lock
without disabling hardirqs. Teach lockdep about this.
Ingo,
Did you update your
http://people.redhat.com/mingo/lockdep-patches/lockdep-combo-2.6.17-rc5-mm1.patch
or did I miss the patch to add the disable_irq_lockdep function?
i've updated it now, please check it out. (i sent the generic
disable_irq_lockdep() bits to lkml separately but forgot to Cc: you)
