Even if the driver-agnostic part of the irq processing can be interrupted
locally, the irq handlers are run sequentially on a given cpu. It does not
leave a lot of room for a deadlock-prone printk().

It _can_ happen but I'd prefer to pinpoint a specific candidate path
where it would have happened.
