    Hold on please. Becouse if you think one step further ->
    not blocking blk_stop_queue() in do_request or more
    precisely at places where the IDE_BUSY get's set 8-) you suddenly get
    completely rid of it if you replace the "back-calls" to do_request() in
    ata_irq_request() and ide_timer_expiry() with blk_start_queue()...
    No direct manipulation whatsever.
