Hi, A few questions/suggestions: - is it still vanilla -rc6-mm1; I've seen on kernel list you tried some fixes around raid? - could you remind this lockdep warning; is it always and the same, always before crash, or no rules? - I've seen you looked after double freeing, but this last debug list warning could suggest locking problems during list modification too. - above git-nfsd and git-net tests should be probably repeated with -rc6-mm1 git versions: so vanilla rc6 plus both these -mm patches only, and if bug triggers, with one reversed; btw., since in previous message you mentioned that 50 packages could be not enough to trigger this, these 54 above could make too little margin yet.
