It looks like the worst that would happen is that some irqs might not be properly released, not the sort of thing that is going to make the system unstable if you don't bug. Can't they just be replaced with (for example): if (WARN_ON(blah)) return; Or even just: netdev_err(adapter->netdev, "bad irq type %d for free\n", intr->type); ~Ryan -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
