    Well I was assuming you'd code this up in the driver not arbitarily - and
    you need to do that for IRQ anyway. So something like


    writel(0xFFFFFFFF, &mdev->irq_mask);
    pci_mark_failed(pdev, PCI_TRY_REPLUG|PCI_TRY_D3);
    spin_unlock(&mylock);
    return -EXPLODED;

    with pci_mark_failed firing off any replug via a work queue
