So there is no output from lockdep, during the rmmod hang ? The rmmod sucks 100% cpu, so it busy loops at some place. Looking at the stack trace this seems to be in: void cancel_rearming_delayed_workqueue(struct workqueue_struct *wq, struct delayed_work *dwork) { while (!cancel_delayed_work(dwork)) flush_workqueue(wq); } which is not really related to timers :) tglx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
